    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: This invention provides a PSA composition comprising a base polymer and a tackifier resin. The base polymer is a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound. The tackifier resin comprises a tackifier resin TH having a softening point of 120° C. or above. The tackifier resin TH comprises a tackifier resin THR1 having an aromatic ring while having a hydroxyl value of 30 mgKOH/g or lower.
