Abstract:
A sealed battery includes a lid closing a container of a sealed battery, an upper current collecting plate, a lead connecting an upper surface to an inner surface of the lid. A welding point of the lead is outside a position corresponding to a periphery of the cap. The lead includes a cylindrical lateral wall part extending vertically, an annular frame portion extending substantially horizontally from a first end of the lateral wall part, and a plurality of supplementary leads that extends substantially horizontally from a second end part of the lateral wall part. The frame portion extends from the first end part in substantially a first direction along a radial direction of the cylindrical lateral wall part, whereas the plurality of supplementary leads extends from the second end part in substantially a second direction opposite to the first direction along the radial direction.
