Original Abstract Submitted

In a battery, each current collector tab includes a root portion, a connection portion, and an intermediate portion. Current collector tabs include a laminated connection portion in which the connection portions are laminated. A current collector terminal includes an inner surface facing a side surface portion of an electrode body, and a side surface disposed along an outer edge of the inner surface. A laminate film is disposed on the side surface. A main surface of the laminated connection portion is joined to the inner surface. In a plan view in an electrode body laminating direction, the current collector terminal includes a base portion including a first end portion corresponding to the position of the inner surface and a second end portion opposite to the first end portion, and a protruding portion protruding from the base portion to an opposite side of the base portion from the electrode body.
