Abstract:
Provided is a pressure sensitive adhesive sheet containing a resin layer on a substrate or a release material, at least a surface (α) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein, when a smooth surface of a light transmissive adherend having a smooth surface is attached to the surface (α), one or more concave portion (G) not kept in contact with the smooth surface exist on the surface (α), and the shapes of the one or more concave portions (G) have irregular shapes. The pressure sensitive adhesive sheet has excellent air escape property capable of readily removing air accumulation that may be formed on attaching to an adherend, and has good pressure sensitive adhesion characteristics.
