Japanese Patent JP7347455

B2

To provide an exterior material for a power storage device that prevents a curl caused by molding.SOLUTION: An external material 10 for a power storage device is rectangular in plan view and composed of a film-like molded laminate that includes at least a base material layer, a barrier layer, and a thermally-adhesive resin layer in this order, and includes a rectangular parallelepiped concave part 100 that faces the thermally-adhesive resin layer in which a power storage device element is accommodated. On a straight line connecting the center of the concave part and a short side of the external material for a power storage device in the shortest distance, the external material for a power storage device includes a first short side curved face part 11A and a second short side curved face part 12A in order from the center of the concave part up to the short side of the external material for a power storage device, and includes a first long side curved face part and a second long side curved face part in order from the center of the concave part up to a long side of the external material for a power storage device. The radius of curvature of the first long side curved face part RB1 is larger than the radius of curvature of the first short side curved face part RA1, and the radius of curvature of the first long side curved face part RB1 is 3.8 mm or more.SELECTED DRAWING: Figure 6
