Abstract: Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer formed of a multilayer structure of three or more layers including a fine particle-containing layer that contains fine particles in an amount of 15% by mass or more, at least a surface (±) 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 the fine particle-containing layer is formed not as the outermost layer of the resin layer, and one or more concave portions exist on the surface (±) and the shapes of the one or more concave portions have irregular shapes. When attached to an adherend, the pressure sensitive adhesive sheet can exhibit excellent air escape property of readily removing air accumulation which may be formed, good blister resistance and good pressure sensitive adhesion characteristics.

Abstract: A sealing sheet having a resin layer comprising a resin part (A) formed by a resin composition containing one or more resins selected from the group consisting of an acrylic-based resin and a urethane-based resin, and a resin part (B) having a water vapor transmission rate measured in conformity with JIS K 7129 of 15 g/m 2 /day or less, in which the resin part (A) and the resin part (B) are present on at least one surface of the resin layer. The sealing sheet excels in a suppressing effect on moisture intrusion of the sealing sheet itself, and, when manufacturing a sealing structure, excels in an effect to prevent moisture intrusion into the sealing structure from between a substrate (adherend) and the sealing sheet.
