Zusammenfassung:	An insulation sheet is disposed between a rectangular housing and an electrode body. A first side wall of the insulation sheet is disposed between a large-area side surface of the rectangular housing and the electrode body. The first side wall includes a first folded portion that is folded along an edge of the first side wall near a sealing plate. The first folded portion extends from an edge of the first side wall near the sealing plate toward a bottom surface of the rectangular housing and is disposed between the large-area side surface and the electrode body in such a way that the first folded portion overlaps the first side wall.
