Summary:PROBLEM TO BE SOLVED: To provide an adhesive which is used in an outer packaging material for batteries, that material is subjected to a drawing process, and which can suppress the generation of delamination between a base material film and a metal foil sheet even under a high-temperature and high-humidity environment.SOLUTION: An adhesive 12 is used in an outer packaging material 10 for batteries, which material includes a base material film 11 and a metal foil sheet 13, when the base material film 11 is stuck to the metal foil sheet 13. The adhesive 12 is characterized in that a displacement rate is less than 3% at 80°C when needle penetration of thermomechanical analysis is measured.
