The electrode terminal includes a terminal part, an external connection part, and a molding resin part. The terminal part is connected to the power generating element. The external connection part contacts with the terminal part. The molding resin part covers the periphery of the connection surface between the external connection part and the terminal part in a state where a part of the external connection part is exposed to outside. The external connection part includes a step part between an outer circumferential portion of a connection surface between the external connection part and the terminal part, and an exposed part exposed from the molding resin part to the outside. The molding resin part covers both the outer circumferential portion of the connection surface and the step part.
