    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 sheet comprising a single PSA layer having a thickness of 100 μm or larger. The PSA layer is formed from a solvent-based PSA composition. When a cross-sectional area vertical to the PSA layer is observed, the PSA layer has fewer than 1.0 bubble of 100 μm size or larger per mm2 of cross-sectional area. When the PSA layer is stored at 80° C. for 30 minutes, the mass of toluene released from the PSA layer is 10000 ppm or less of the mass of the PSA layer.

    Abstract: Provided is a double-faced pressure-sensitive adhesive sheet comprising a non-woven fabric substrate, and a pressure-sensitive adhesive layer provided on each of a first face and a second face thereof. The double-faced pressure-sensitive adhesive sheet has a mass per area of 150 g/m2 or smaller. 85% or more of its mass corresponds to the combined mass of the pressure-sensitive adhesive layers. The non-woven fabric substrate comprises Manila hemp fibers of 6 μm diameter or larger at a proportion of 25% or more by the number of threads of its constituent fibers.
