Abstract: An axial lead extending on a principal surface of a flat tab includes a main body part having a diameter and a connection part. The connection part includes a first part located adjacent to the main body part and a second part located from the first part and the end part. The first part includes a weld part welded to the flat tab and has a first thickness less than the diameter. The second part includes a non-weld part not welded to the flat tab and has a second thickness equal to or less than the first thickness. The second part is formed by pressing the end part of the axial lead, the end part having been raised when resistance welding is performed on the axial lead and the flat tab.
