The present invention has, on a base material or a release material, a resin layer comprising a multilayer structure of three or more layers including a microparticle-containing layer containing 15 mass% or more of microparticles, and at least the number of The surface (α) of the backing layer is a pressure-sensitive adhesive sheet, the fine particle-containing layer is formed other than the outermost layer of the resin layer, and a concave portion is present on the surface (α), and the concave portion has an irregular shape. to be. The said adhesive sheet has the outstanding air release property which can remove easily the air stagnant which may generate|occur|produce when it adheres to a to-be-adhered body, and also has favorable blister resistance and adhesive property. |
