Abstract

A pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer, at least a surface (α) of the resin layer being opposite to the side of the substrate or being opposite to the side which the release material is provided, having pressure sensitive adhesiveness, the surface (α) having one or more concave portions, the concave portions having irregular shapes. The pressure sensitive adhesive sheet has an excellent air escape property capable of easily removing air accumulation that may be formed on attaching to an adherend, and is excellent in pressure sensitive adhesion characteristics.
