Abstract: This invention provides a PSA sheet that allows prevention or reduction of damage such as fracture with efficient stretch removability. A stretchable PSA sheet is provided, comprising a PSA layer and a film-like substrate supporting the PSA layer. The PSA sheet has a long section. The long section has a tapered segment that extends, tapering to a first end of the length direction and the film-like substrate has a minimum cross-sectional area larger than 0.30 mm2 in the tapered segment.

Abstract: A pressure-sensitive adhesive sheet including a plastic substrate having a thickness of more than 0 μm and less than 2.0 μm and a pressure-sensitive adhesive layer on at least one side of the plastic substrate. The pressure-sensitive adhesive layer contains an acrylic polymer or a rubber-based polymer in an amount of 50 wt % or more relative to a total amount of the pressure-sensitive adhesive layer. The acrylic polymer is formed of a monomer mixture containing the specific alkyl (meth)acrylate monomer in an amount of 50.0 to 99.8 wt % relative to a total amount of monomer components and a polar group-containing monomer in an amount of 0.01 to 20 wt % relative to the total amount of monomer components.
