摘要： Power supply device includes battery stack in which a plurality of prismatic battery cells are stacked, end plate having a rectangular shape in plan view and having a pressing surface that covers an end surface of battery stack, and fastening member that fastens battery stack. End plate has, on a pressing surface, flat pressing regions respectively formed on end edge sides in the up-down direction, and bead region formed on the middle side in the up-down direction and bent in a shape protruding toward the back surface side of the pressing surface. Thus, strength can be improved by changing a shape in which bead region is formed in the middle while pressing regions that presses battery stack remains on end plate, which enables end plate having high strength to be provided at low cost.
