Abstract
The present invention relates to a pressure-sensitive adhesive tape for battery containing: a substrate; and a pressure-sensitive adhesive layer provided on at least one side of the substrate, in which the pressure-sensitive adhesive tape has a thickness change ratio of 20% or less after immersion in a mixed solvent of ethylene carbonate/diethyl carbonate [former/latter (volume ratio)=1/1] at 60° C. for 8 hours; and a 180° peeling adhesive strength (against aluminum foil, peel temperature: 25° C., peel rate: 300 mm/minute) of 0.5 N/10 mm or more after the above immersion.
