Abstract: Provided is a pressure-sensitive adhesive (PSA) sheet having a low relative dielectric constant, satisfactory metal corrosion preventing property, and excellent member holding performance. The present invention provides a PSA sheet having a PSA layer including a base polymer and a rust inhibitor. The base polymer is an acrylic polymer, and monomeric components constituting the acrylic polymer comprise a (meth)acrylate having an alkyl group having 5 or more carbon atoms at an ester end at 50% by weight or more of the monomeric components. The PSA layer has a relative dielectric constant of 3 or less at 300 kHz.

Abstract: Provided is a pressure-sensitive adhesive (PSA) sheet including a PSA layer formed from a PSA composition including a base polymer, crosslinking agents of two or more species having mutually different types of crosslinkable functional groups, and an azole-based rust inhibitor. Here, one of the crosslinking agents of two or more species is an isocyanate-based crosslinking agent. Monomeric components constituting the base polymer include a carboxy group-containing monomer. The amount of the azole-based rust inhibitor in the PSA layer is less than 8 parts by weight with respect to 100 parts by weight of the base polymer.

Abstract: Provided are a graphite pressure-sensitive adhesive tape that is suitable for improving thermal efficiency; and a graphite pressure-sensitive adhesive tape with a release liner, which contains the pressure-sensitive adhesive tape. This graphite pressure-sensitive adhesive tape with a release liner is provided with a graphite pressure-sensitive adhesive tape, which has a first pressure-sensitive adhesive layer and a graphite layer in this order, and a release liner that protects the surface of the first pressure-sensitive adhesive layer. The first pressure-sensitive adhesive layer has a single layer structure.
