摘要： This power storage device comprises an electrode body and an exterior body. The exterior body seals the electrode body. The exterior body is configured from a film-like exterior member. The exterior body includes a first sealed part sealed by joining surfaces which face each other in a state of being wound around the electrode body. The area of a first surface is larger than the area of a second surface. The first sealed part does not overlap the first surface in a plan view. The exterior body is configured from a laminate comprising at least a base material layer, a barrier layer, and a heat-fusible resin layer in the stated order. The barrier layer includes an aluminum alloy foil satisfying a composition of 0.2-2.0 mass% of Fe, and 0.1-5.0 mass% of Mg.
