An adhesive sheet having a resin layer on a base material or a release agent and having at least a surface (α) of the resin layer on the side opposite to the side on which the base material or the release agent is provided is a tacky sheet, And a concave portion G that does not contact the smooth surface exists on the surface a when the smooth surface is attached and the concave portion G is irregular in shape. The pressure-sensitive adhesive sheet has excellent air releasing properties, which can easily remove air build-up which may occur when adhered to an adherend, and good adhesive properties. |
