Abstract: An adhesive film which is for a metal terminal and exhibits high adhesion strength to a metal terminal, when heated and pressurized a plurality of times before being adhered to the metal terminal. This adhesive film for a metal terminal is interposed between: a metal terminal electrically connected to an electrode of a power storage device element; and an exterior material for a power storage device that seals the power storage device element. The adhesive film for a metal terminal has a tensile elastic coefficient A of at least 490 MPa, when measured in an environment of a temperature of 25° C., after being left standing for 12 seconds in a heating and pressurizing environment of a temperature of 180° C. and a surface pressure of 0.0067 MPa, and after being left standing for 1 hour in an environment of a temperature of 25° C.
