The present invention has a resin layer on a substrate or a peeling member, and at least the surface (α) of the resin layer on the side opposite to the side where the base material or the peeling agent is installed has tackiness and a concave portion exists on the surface , And a standard deviation (?) With respect to an average luminance value of the surface (?) Is not less than 10.0. The pressure-sensitive adhesive sheet has excellent air releasing properties, which can easily remove air build-up that may occur when adhered to an adherend, and has excellent adhesive properties. |
