Abstract: A pressure-sensitive adhesive sheet has a substrate and a pressure-sensitive adhesive layer laminated on at least one side of the substrate. The sheet is configured such that: pressure-sensitive adhesive force N1, occurring after the pressure-sensitive adhesive layer is attached to a stainless steel plate (430 BA plate) and is left at 23° C. for 10 seconds, is 1.0 [N/20 mm] or less; pressure-sensitive adhesive force N2, occurring after the pressure-sensitive adhesive layer is attached and is aged at 80° C. for 5 minutes, is 3.0 [N/20 mm] or more; and N2/N1 is 5.0 or more.
