An inner core material is arranged in the inside of the outer packaging material. The outer packaging material has an outer packaging laminate material including a metal heat transfer layer and a resin thermal fusion layer on a surface side of the heat transfer layer. The outer packaging laminate materials form a bag shape by integrally joining the thermal fusion layers along the peripheral edge portions. The inner core material includes the inner core laminate material with a metal heat transfer layer and resin thermal fusion layers on surface sides of the heat transfer layer. The thermal fusion layers of a concave portion bottom and a convex portion top of the inner core material and the thermal fusion layers of the outer packaging laminate material are integrally joined.

Abstract: A package for a power storage device includes at least one laminated packaging material having first and second sections. The packaging material includes a metallic foil layer, a heat-resistant resin layer, and a heat-fusible resin layer. In a state in which the heat-fusible resin layers of the first and second sections are faced, peripheral edges thereof are heat-sealed to form a storage chamber for accommodating a device main body. One of the sections is extended outside the storage chamber to form a conductive flange having an exposed heat-fusible resin layer. The conductive flange is provided with an external conductive section in which the heat-fusible resin layer is partially removed to expose the metallic foil layer. The packaging material having the external conductive section is provided with an internal conductive section in the storage chamber in which the heat-fusible resin layer is partially removed to expose the metallic foil layer.
