LAMINATED BATTERY AND MANUFACTURING METHOD THEREFOR

摘要

A laminated battery provided with an electricity-producing element and an outer case. The electricity-producing element contains a positive electrode, a negative electrode, and an electrolyte. The outer case comprises two sheets of laminating film and includes the following: a containing section that contains the electricity-producing element; and a sealing section that is formed around the edge of the containing section by bonding the sheets of laminating film to each other. Corners are formed along the boundary between the containing section and the sealing section, and an adhesive resin layer in the sealing section is thicker in corner regions near the aforementioned corners than in other regions.
