Abstract
A sealed battery includes a current-collecting terminal member; a gasket that electrically insulates a lid member and the current-collecting terminal member from each other; and a connection member that connects the current-collecting terminal member and an external terminal member. The connection member and the current-collecting terminal member are connected by swaging the second end of the current-collecting terminal member to an insertion hole of the connection member. The lid member has a lid-side protruded portion that compresses the gasket. The current-collecting terminal member has a terminal-side protruded portion that compresses the gasket. A gasket-side area of the lid-side protruded portion, a gasket-side area of the terminal-side protruded portion, and an area of a surface of the current-collecting terminal member which faces and contacts the gasket, except the terminal-side protruded portion, are different in size from each other.
