    Abstract: To reduce influence of external force on a current collection tab lead and a current collection tab in a laminated cell type battery. A single film of an exterior body contacts and covers a top surface, a bottom surface, and two side surfaces of a battery perpendicular to an end surface of the battery from which a current collection tab and a current collection tab lead are provided to extend, covers the end surface of the battery from which the current collection tab and the current collection tab lead protrude, and is folded in from both short sides of the end surface such that triangular pyramid-shaped spaces are formed on both sides. A reinforcement member is arranged in and joined to each triangular pyramid-shaped space.
