Abstract
A connector for connecting a first cell and a second cell of a battery in series. Each one of the first cell and second cell has (a) a metal casing as the negative electrode, and (b) a metal electrode installed at one end of the casing, including a first flat portion as the positive electrode. The connector has a side wall capable of fitting the casing inside, and a second flat portion orthogonal to the side wall. A first projection for welding to the electrode member is installed on the second flat portion. A second projection for welding to the casing is installed on an inside surface of the wall. The first projection of the electrode abuts against the first surface of the first cell and are welded together. The side wall of the connector is coupled to the outside of the casing of the first cell, and the second projection of the connector abuts against the surface of the casing of the second cell, and are welded together.
