1. A battery cover member, comprising:
a metallic electrode terminal; and a metallic cover member having a through hole and an insulating resin member, in which the electrode terminal inserted into the through hole and the cover member are integrally bonded together by the insulating member, wherein at least a sealing area of the electrode terminal that adheres to the insulating member has a circular columnar shape or an elliptically columnar shape, wherein the electrode terminal is integrally formed from one columnar rod member by plastic processing, and wherein the electrode terminal has a flat-plate-shaped collector terminal connected to an electrode member, a flat-plate-shaped external terminal connected to a connect member, and a joint that is formed into a shape of a three-dimensional line of flexure and that connects the collector terminal to the external terminal.
