Abstract
A battery pack includes a battery stack including a plurality of battery cells and a case member in which the battery stack is housed. The case member includes an end wall part located on one end of the battery stack in a stacking direction and continuously integrated with a floor part, and a mounting-shape part located on an opposite end from the end wall part and configured to mount a panel-shaped member. The battery stack is retained in the case member while being held by compression between the end wall part and the end panel on the other end. The end panel is pressed against the mounting-shape part in a direction away from the end wall part by compression reaction force of the battery stack, and fixed therein.
