Abstract: A pressure-sensitive adhesive sheet according to the present invention includes a base including a metal layer, a first plastic film layer A, and a second plastic film layer B and a pressure-sensitive adhesive layer on a surface of the second plastic film B. The metal layer is positioned between the first plastic film layer A and the second plastic film layer B. The metal layer has a thickness of 2 μm to 15 μm. A total of a thickness Ta of the first plastic film layer A and a thickness Tb of the second plastic film layer B is within a range of 25 μm to 70 μm.

Abstract: There is provided a double-sided pressure-sensitive adhesive sheet including a pressure-sensitive adhesive body having pressure-sensitive adhesive faces (a) and (b) on both sides thereof, and a release liner (A) provided at least on the pressure-sensitive adhesive face (a) of the pressure-sensitive adhesive body. The release liner (A) includes a paper-based base material and a release layer on a face of the paper-based base material, the release layer being in contact with the pressure-sensitive adhesive face (a). The ratio of an interlayer strength of the release liner (A) with respect to a peeling force of the release liner (A) in a peeling test at 90° with respect to the pressure-sensitive adhesive face (a) is 15 or more. The double-sided pressure-sensitive adhesive sheet may preferably be used as a double-sided pressure-sensitive adhesive sheet for a flexible printed circuit board.
