It is a front view which shows the double-sided adhesive tape used for the molded article which can be adhere | attached on the adherend which concerns on Example 3 of this invention. 12 is a cross-sectional view of the double-sided adhesive tape taken along the line II-II of FIG. 11. It is explanatory drawing which shows the process of forming the extending | stretching part of thin shape in the release paper of a double-sided adhesive tape.

As shown in FIG. 11 and FIG. 12, in the third embodiment, the double-sided adhesive tape 230 is formed of the double-sided adhesive tape body 31, the release paper 240, and the carrier sheet 35. A predetermined portion of the release paper 240 made of a thermoplastic resin sheet (for example, a polyethylene sheet) adhered to the adhesive layer 33 on one side of the double-sided adhesive tape body 31 bent along the convex edge edge of the back surface ( In the part corresponding to the convex corner edge of the back surface of the molded article main body, a drawing portion 248 having a thin thickness and a thin thickness extending in the bending direction is formed as compared with other portions of the same release paper 240.

For example, as shown in FIG. 13, in the state which the carrier sheet 35 of the double-sided adhesive tape 230 faced down, and the release paper 240 faced up, the linear shape of the presser 60 heated was carried out. While pressing the edge of the blade 61 at a predetermined position on the release paper 240, the thickness of the substrate 32 of the double-sided adhesive tape body 31 made of foamed urethane or the like is elastically compressed, and the pressed portion of the release paper 240 is pressed to extend the thickness. The stretching portion 248 forming a thin shape is formed.

The thickness B of the thinly stretched portion 248 is formed to be a few minutes thinner than the thickness A of the other portion.

Since the other structure of this Embodiment 3 is comprised similarly to Embodiment 1, the description is abbreviate | omitted.

Therefore, according to the double-sided adhesive tape 230 according to the third embodiment, the release paper 240 is convexly curved along the convex edge edge of the back surface of the molded body in the stretched portion 248 having a thin thickness. For this reason, it can prevent by the extending part 248 of the release paper 240 that tensile stress remain | survives in a bending direction. For this reason, the restoring force of the release paper 240 can be reduced, and the release paper 240 can be prevented from peeling off partly from the adhesive layer 33 of the double-sided adhesive tape main body 31.

In addition, this invention is not limited to the said Examples 1-3, It can also be implemented in various forms within the range which does not deviate from the summary of this invention.

For example, the stretched portion 248 having a thin thickness of the separating portion 42 of the release paper 40 of the first embodiment or the release paper 240 of the third embodiment has an edge of the convex edge of the molded article body 21 ( It is preferable to form a plurality of strings parallel to each other along 26). In this case, since the generation of the tensile stress in the bending direction of the release papers 40 and 240 can be satisfactorily prevented by the plurality of lines of the separating portion 42 or the thinner drawing portion 248, the release paper 40 By reducing the restoring force of the 240, it is possible to more effectively prevent the partial peeling of the release paper (40, 240).
