Abstract:
The present invention relates to a double-sided pressure-sensitive adhesive tape or sheet, containing a heat-releasable pressure-sensitive adhesive layer containing a heat-expandable microsphere on one side of a substrate, and a pressure-sensitive adhesive layer for temporary fixing on another side of the substrate, in which the pressure-sensitive adhesive layer for temporary fixing has a tensile pressure-sensitive adhesive strength of 2.0 to 20 N/20 mm in width and an amount of displacement of 0.3 mm/20 mm in width or less, and the pressure-sensitive adhesive layer for temporary fixing is crosslinked with an isocyanate or epoxy crosslinking agent.
