Abstract

A power storage device is constituted by a laminate including, in the stated order, at least a substrate layer, a barrier layer, and an inside layer. The inside layer is provided with an adhesive layer and a heat-sealing resin layer from the barrier layer side; and if dynamic viscoelasticity is measured by tension with respect to the inside layer, the growth rate at 80° C. is 8.0% or lower.
