  As an example, the conductive portion 30 is configured to include a conductive substance having conductivity, and is configured to include, for example, the conductive wire 3. The conductive wire 3 may be a fiber mainly containing conductive metal or carbon.

  The conductive wire 3 is installed in the base part 50 so that the root part 12 of the 1st fiber 1 and the root part 22 of the 2nd fiber 2 may be connected as an example. The conductive wire 3 may electrically connect the first fiber and the second fiber, and may be provided so as to be buried in the base portion 50 (between the skin side surface 51 and the back side surface 52), or the base portion 50 or. It may be provided so as to connect the first fiber and the second fiber on the back side of the weak current tool 100.

  Note that the substance that acts as an electrode and the substance that acts as a conductive portion are not limited to metals. Any combination that can generate a weak current in the living body by utilizing the difference in the potential difference (ionization tendency) is not limited to a combination of different metals, and a combination of conductive polymer, conductive oxide, etc. Good. Moreover, what is called a semiconductor may be used.

  The base 50 is a sheet-shaped member made of an insulating material here. A woven fabric or knitted fabric may be used for the base 50, or silicon rubber, paper, cloth, sponge, or the like may be used. The base 50 may be formed into a mesh sheet with these materials. The base 50 may include a material that emits far infrared rays or a material that contains carbon or the like.

  As shown in FIG. 2, in the weak current tool 100, the first electrode portion 10 is composed of a portion (area) where the first fiber 1 is arranged, and the second electrode portion 20 is arranged where the second fiber 2 is arranged. It is composed of the part (area) that exists. The first electrode portion 10 has a plurality of protrusions 11 on the skin side, and the second electrode portion 20 has a plurality of protrusions 21 on the skin side.

  The first electrode portion 10 and the second electrode portion 20 are arranged with a gap (hereinafter also referred to as “electrode portion gap”). The electrode portion gap is a gap sufficient to insulate the two on the skin side. In other words, in the weak current tool 100, the insulating portion is formed by the electrode gap. The electrode portion gap is, for example, 3.0 mm to 50.0 mm. When it is installed on the innerwear and the back or the like is the target site, the electrode part gap is preferably 5.0 cm to 30.0 cm.

  Here, the conductive portion 30 is installed so as not to be exposed to the skin side, and as an example, as shown in FIG. 2, is provided in a closed loop shape along the surface direction of the base portion 50. Although not shown, the conductive portion 30 may be provided so as to form a plurality of loops that spread from the inner side to the outer side at regular intervals.

  As shown in FIG. 3, as an example, the first fibers 1 are installed on the base 50 by weaving or knitting the first fibers 1 into the base 50. In FIG. 3, the root portion 12 is shown exposed from the skin side surface 51, but this is for convenience of description. Here, as shown in FIG. 1, the root portion 12 is located on the skin side. Not exposed.

  For example, by using one first fiber 1 and repeating the work of pulling out from the base portion 50 in a substantially inverted U shape to the skin side with a gap (hereinafter also referred to as “first fiber gap”), a plurality of skins can be formed on the skin side. The substantially inverted U-shaped protrusions 11 are formed in a line, and a plurality of perforated roots 12 are formed in a line on the back side. The first electrode portion 10 is formed by installing the plurality of first fibers 1 on the base portion 50 in this manner. Further, if the pull-out direction of the first fiber 1 is set to be substantially perpendicular to the base portion 50, the protrusion 11 is provided substantially perpendicular to the skin side surface 51 of the base portion 50. Although not shown, the second fiber 2 can be installed on the base 50 in the same manner as the first fiber 1.

  In the weak current tool 100, the protruding portion of the electrode portion (first electrode portion and second electrode portion) that bulges in a substantially inverted U shape comes into contact with the skin, and a gap is formed between the installation surface of the root portion and the skin. Therefore, the stuffiness of the skin can be suppressed. Further, the contact area between the electrode portion and the skin is small, and skin irritation can be suppressed. Further, by forming the protruding portion in a substantially inverted U shape, the contact portion with the skin is bent, and the contact with the skin becomes easier.

  Further, if a material having a spring property such as a drawing material is used, the repulsive force can be maintained. In addition, it is unlikely to cause fatigue or breakage. In addition, the contact part moves due to body movements, etc., and the contact position of the electrode part on the skin changes, so it is difficult to concentrate the skin irritation, the skin irritation is reduced, and the effect range is averaged. Cheap.

  The protrusion 11 of the first fiber 1 may be linearly provided on the skin side surface 51 of the base 50. For example, in the above-mentioned operation, the first fiber 1 can be formed into two linear protrusions 11 by pulling out the first fiber 1 in a substantially inverted U shape and then cutting the upper end. Even when the protrusion is formed in a linear shape, the protrusion is in contact with the skin and a gap is formed between the installation surface of the root and the skin, so that the air permeability is good and the stuffiness of the skin can be suppressed. Further, the contact area between the electrode portion and the skin is small, and skin irritation can be suppressed.

  The first fiber 1 and the second fiber 2 may be provided so as to project from the base portion 50. For example, the first fiber 1 and the second fiber 2 may be sewn to the base portion with a gap or may be linearly drawn from the base portion 50. . Alternatively, the root may be exposed from the base 50 by being installed along the side surface of the skin.

  The conductive portion 30a may be installed so as to be wired longer than a straight line distance including a plurality of slack portions 37a having a fine curved or polygonal line shape. Accordingly, it is possible to prevent the conductive portion 30a from breaking due to expansion and contraction of the base portion 50 or the like, or breakage, pushing, or impact of the base portion 50. The plurality of slack portions 37a may be formed by a knitting method such as rubber knitting (also referred to as rib knitting or rib knitting).

  The conductive portion 30a, the second fiber 2 and another fiber may be woven together. Although the conductive portion 30a is exposed on the back side surface 52 in the drawing, the conductive portion 30a may be installed so as to be buried in the base portion 50. Further, the exposed conductive portion 30a may be woven and covered with an insulating fiber having a long bristle in a bristle length.
