Abstract: A pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer, at least a surface (α) of the resin layer being opposite to the side of the substrate or being opposite to the side which the release material is provided, having pressure sensitive adhesiveness, the surface (α) having one or more concave portions, the concave portions having irregular shapes. The pressure sensitive adhesive sheet has an excellent air escape property capable of easily removing air accumulation that may be formed on attaching to an adherend, and is excellent in pressure sensitive adhesion characteristics.

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 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/m2/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.
