Abstract

Provided is a pressure sensitive adhesive sheet having 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 has pressure sensitive adhesiveness, wherein one or more concave portions exist on the surface (α), and a standard deviation (σ) based on a mean brightness value of the surface (α) is 10.0 or more. When attached to an adherend, the pressure sensitive adhesive sheet can readily remove air accumulation to be formed and therefore exhibits excellent air escape property, and has good pressure sensitive adhesion characteristics.
