Summary:A power supply device includes battery cells each having a rectangular external shape, a separator disposed between the battery cells, a pair of end plates that are disposed on respective ends of a battery assembly in which the separator and the battery cells are stacked, and a bind bar that binds the pair of end plates. The separator has insulating rib parts that protrude from both surfaces of the separator, and the insulating rib parts of the separator stacked on each surface of the battery cell are stacked on each other on a bottom surface of the battery cell. The insulating rib parts are stacked on each other on the bottom surface of the battery cell by inserting an insertion rib provided in one of the stacked insulating rib parts into an insertion groove provided in the other of the stacked insulating rib parts.
