Abstract: A packaging material for a power storage device includes a structure made up of a cover layer, a barrier layer, a sealant adhesive layer, and a sealant layer laminated in this general order. In the packaging material, the barrier layer has an aluminum foil layer and an anticorrosion treatment layer that is provided to a sealant layer side surface of the aluminum foil layer and faces the sealant adhesive layer. The sealant layer side surface of the aluminum foil layer has a 60° glossiness that is 690 or less in both MD and TD, and has a difference in 60° glossiness between MD and TD that is 100 or less.

Abstract: A packaging material for a power storage device having a laminate structure in the following order including a substrate layer, a first adhesive layer, a metal foil layer, a second adhesive layer, and an inner layer containing a polyester-based resin. The inner layer has a melting peak temperature during melting in a range of 160 to 280° C. which is measured by a differential scanning calorimeter. The substrate layer has a melting peak temperature that is higher than the melting peak temperature of the inner layer.
