Original Abstract Submitted

A battery includes an electrode body, current collector tabs, a current collector terminal, and a laminate film. Each current collector tab includes a root portion that is an end portion on the electrode body side, a connection portion for connecting to the current collector terminal, and an intermediate portion connecting the root portion and the connection portion. The current collector tabs include a laminated connection portion in which the connection portions are laminated in a thickness direction. The current collector terminal includes an inner surface facing a side surface portion of the electrode body, and a side surface disposed along an outer edge of the inner surface. The laminate film is disposed on the side surface of the current collector terminal. A main surface of the laminated connection portion is joined to the inner surface. A spacer member is disposed between the inner surface and the side surface portion.
