Abstract:
The present invention provides an adhesive film for metal terminals, said adhesive film being capable of achieving high sealing performance between itself and a thermally fusible resin layer of an outer covering material in a short time, while being suppressed in collapse due to heat sealing and having excellent followability. An adhesive film for metal terminals, said adhesive film being interposed between a metal terminal that is electrically connected to an electrode of an electricity storage device element, and an outer covering material for electricity storage devices, said outer covering material sealing the electricity storage device element. This adhesive film for metal terminals is configured from a multilayer body which is sequentially provided, in the following order, with: a first polyolefin layer that is arranged on the metal terminal side; a base material; and a second polyolefin layer that is arranged on the outer covering material for electricity storage devices side. The heat of fusion ΔH1 of the first polyolefin layer and the heat of fusion ΔH2 of the second polyolefin layer as determined in accordance with JIS K 7122 (2012) satisfy the relational expression ΔH1 > ΔH2; and the heat of fusion ΔH3 of the base material as determined in accordance with JIS K 7122 (2012) is 70 J/g or more.
