Abstract
In an assembled battery 1 disclosed herein, each of adjacent single cells 10 is electrically connected by a busbar 30. The busbar 30 of the assembled battery 1 includes a plate-shaped base portion 32 which extends along an arrangement direction X, and a joining projection 36 extending along electrode terminals 12 and 14 and a locking biasing portion 38 which locks the electrode terminals 12 and 14 and the busbar 30 to each other and which biases the electrode terminals 12 and 14 toward the joining projection 36 are formed at both ends of the base portion 32. Furthermore, in the assembled battery 1 disclosed herein, the electrode terminals 12 and 14 and the joining projection 36 come into surface contact with each other and tip portions 12a and 14a of the electrode terminals 12 and 14 and a tip portion 36a of the joining projection 36 are welded to each other. Accordingly, welding between the electrode terminals 12 and 14 and the busbar 30 can be performed in an appropriate manner.
