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.

Abstract: A pressure sensitive adhesive sheet including, on a substrate or a release material, a resin layer including a resin part (X) containing a resin as a main component, and a particle part (Y) consisting of fine particles and having a surface (α) having pressure sensitive adhesiveness and one or more concave portions. When the surface (α) of the resin layer is adhered to a smooth surface of a light transmissive adherend to give a laminate, the areal ratio (S1) of the attached area adhered to the smooth surface to the surface (α) is 10 to 95% at 23° C. and 50% RH, and the area increase rate {[(S2−S1)/S1]×100} is −10 to 20% after heating of the smooth surface by statically leaving the laminate at 80° C. for 30 minutes.
