摘要：
An adhesive film for a metal terminal, which is to be interposed between a metal terminal electrically connected to an electrode of a power storage device element and a power storage device packaging material for sealing the power storage device element, wherein the adhesive film for a metal terminal comprises a laminate sequentially including a first polyolefin layer disposed on the metal terminal side, a base material, and a second polyolefin layer disposed on the power storage device packaging material side, the laminate has a first adhesive layer between the first polyolefin layer and the base material, has a second adhesive layer between the second polyolefin layer and the base material, or has both the first adhesive layer and the second adhesive layer, the base material has a melting peak temperature of 135°C or more, and at least one of the first adhesive layer and the second adhesive layer has a melting peak temperature of 100°C or less.
