ASSEMBLED BATTERY AND MANUFACTURING METHOD OF ASSEMBLED BATTERY

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