Title: ADHESIVE SHEET AND METHOD FOR PRODUCING ADHESIVE SHEET
Abstract:
Provided is an adhesive sheet comprising a resin layer on a base material or a release material, wherein at least a surface (α) of the resin layer on the opposite side from the side where the base material or the release material is provided has adhesive properties. Recesses and a flat surface are present on the surface (α). When a region (P) on the surface (α) surrounded by a 5-mm-side square is selected discretionarily and two cross sections of the adhesive sheet are obtained by cutting the region (P) by planes that pass through the respective diagonal lines of said square and that are perpendicular to the region (P) on the surface (α), at least one of the cross sections (P1) has: a plurality of recesses on the surface (α) side of the cross section (P1), the respective shapes of the cut sections of the recesses being different from one another; and a flat part that corresponds to the cut section of the flat surface present in the region (P) on the surface (α), the flat part being substantially parallel to the surface of the base material or the release material.
