[1-1-2] Configuration of peeling tape 17

Next, a specific configuration of the aforementioned release tape 17 will be described. FIG. 7 is a plan view after the protective film 15 and the release tape 17 are extracted. In the following description, expressions such as up, down, left, and right are used based on the paper surface of FIG. 7.

The release tape 17 has a J shape. The release tape 17 is configured by physically connecting the first member 17A, the second member 17B, the third member 17C, and the tongue 17D in this order. In addition, although the first members 17A to 17C are individually defined in the present embodiment for convenience of explanation, the first members 17A to 17C are actually made of the same common material.
