セパレータを設けておくことが有利である。<Prior Art> A double-sided pressure-sensitive adhesive tape using a base material such as rubber and / or synthetic resin-based foam, soft rubber, or thick non-woven fabric as a support is generally used for applications requiring buffering property. In order to facilitate the peeling after the sticking, a double-sided pressure-sensitive adhesive tape which is a composite support obtained by laminating a film-like base material having a high tensile strength and a large Young's modulus on the base material having the buffer property is used. It Such a double-sided pressure-sensitive adhesive tape is adhered with the base material surface side having a large Young's modulus as the sticking surface side so that no tape piece remains on the sticking surface. From the viewpoint of workability of attachment, it is advantageous to provide a separator on the pressure-sensitive adhesive layer on the side of the buffering base material having a small Young's modulus.

能が害されるという問題がある。<Problems to be solved by the invention> However, when a double-sided adhesive tape made of such a support is wound on a core with the separator as the outer surface, the Young The side of the base material having the lower rate is stretched, and the separator is also wound along the side of the base material. Therefore, when the tape is rewound, the base material having a small Young's modulus shrinks to the same length as the base material having a large Young's modulus, but the separator is generally made of paper or a synthetic resin film having a large Young's modulus. Therefore, it is not possible to follow such contraction of the base material, the separator floats up from the support, and the workability of sticking deteriorates, and the adhesive function of the pressure-sensitive adhesive layer is reduced due to the inclusion of foreign matter from this raised part. There is a problem of being harmed.
