PROBLEM TO BE SOLVED: To provide a packaging material for a storage battery having excellent electrolytic solution resistance.SOLUTION: In a packaging material 1 for a storage battery, a substrate layer 11, a first adhesive layer 12, a metal foil layer 13, an anti-corrosion processing layer 14, a second adhesive layer 15, and a sealant layer 16 are sequentially laminated, and at least the second adhesive layer 15 is an adhesive resin layer containing adhesive resin and a metal composition. The metal composition satisfies a relationship of V≤V+2.0 (here, Vis a standard electrode potential of the metal composition (unit: V) and Vis a standard electrode potential of the metal foil layer 13 (unit: V)). A ratio of the metal composition to a total amount 100 mass% of the adhesive resin and the metal composition in the adhesive resin layer is 0.05-95 mass%. |
