PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape for a battery which exhibits slight adhesiveness at room temperature so that temporary fixing is possible and excellent adhesiveness through thermocompression bonding, does not peel off from an adherend even in an electrolytic solution, and is less likely to cause deterioration of the electrolytic solution.SOLUTION: A pressure-sensitive adhesive tape for a battery contains a pressure-sensitive adhesive layer on at least one surface of a substrate. The pressure-sensitive adhesive layer has a thickness from 2 μm to 100 μm. The 180° peeling adhesive force toward an aluminum foil after pressure bonding at 25°C is 0.05 N/10 mm or more, and the 180° peeling adhesive force toward an aluminum foil after thermocompression bonding at or above 30°C below 200°C is 0.5 N/10 mm or more. In preferred embodiments, the pressure-sensitive adhesive layer contains a thermoplastic elastomer. |
