A battery is provided to stabilize contact state of a current collector and a terminal, to suppress poor contact when impact such as falling is applied, and to ensure good sealability of case and quality. A battery comprises a terminal(4) installed at a lid passing through the lid of a battery case; a current collector(7) which contains through holes(72) passing through a terminal, is arranged at the internal side of the lid, and is welded to the terminal by swaging the end part of the terminal passing through the through holes; and an insulating material interposed between the terminal, the current collector and the lid. |
