Abstract: The present invention provides a double-faced pressure-sensitive adhesive sheet comprising a foam substrate, pressure-sensitive adhesive layers provided on a first face and a second face of the foam substrate, and having an overall thickness t of 400 μm or smaller. At least one of the pressure-sensitive adhesive layers is constituted with a rubber-based pressure-sensitive adhesive comprising, as a base polymer, a block copolymer of a mono-vinyl-substituted aromatic compound and a conjugated diene compound.

Abstract: The present invention provides a pressure-sensitive adhesive composition comprising a base polymer and a tackifier resin. The base polymer is a block copolymer of a mono-vinyl-substituted aromatic compound and a conjugated diene compound. The tackifier resin comprises a low softening point resin having a softening point below 120° C. and a high softening point resin having a softening point of 120° C. or above. The high softening point resin comprises a terpene-phenol resin.
