(Embodiment 6: Explanation regarding application of base tape 21 to adherend)
With reference to FIGS. 24 to 27, the attachment of the base tape 21 to the adherend 52 will be described. 24 to 27 are first to fourth application process diagrams of the base tape on the adherend 52. As shown in FIGS. 21 to 23, the tape piece 202 developed from the tape roll body 200 is shown. Fig. 2 shows a form in which the piece 21a is attached to the adherend 52. Here, the peeling mount 24 is temporarily attached to the piece 21a.

  As shown in FIG. 24, the piece 21a developed from the tape roll body 200 and the attachment position of the adherend 52 are relatively aligned. An individual piece 21 a is disposed on the adherend 52. As shown in FIG. 25, from the upper part of the piece 21a, the pressing head 62 is brought into contact with the piece 21a and pressed in the direction of the adherend 52 (in the direction of arrow D in the figure).
