Abstract
According to one embodiment, a connecting busbar includes a pair of first connecting portions provided on first end portions, a pair of second connecting portions provided on second end portions, and a coupling portion that couples the first end portions and the second end portions. Each of the first connecting portions and the second connecting portions is provided with projecting portions that project toward each of positive electrode terminals and negative electrode terminals, and a connecting opening portion provided on a tip end of the projecting portion. The projecting portion is joined to the positive electrode terminal and the negative electrode terminal by performing welding such as laser welding on a thinned portion in a state that a surface of a curved portion contacts with the positive electrode terminal and the negative electrode terminal while the connecting opening approaches the positive electrode terminal and the negative electrode terminal.
