The power supply device includes a plurality of battery cells each having a rectangular outer shape; separators each interposed between the battery cells and insulating mutually adjacent battery cells; and fastening members for fastening a battery cell stack including the alternately stacked battery cells and the separators. The separator includes a sandwiching plate portion disposed between the facing principal surfaces of the mutually adjacent battery cells, and a plate-like bottom-surface cover portion provided to both surfaces of the sandwiching plate portion, at a lower end of the sandwiching plate portion, and protruding in a stacked direction of the battery cells to cover bottom surfaces of the battery cells. The bottom-surface cover portions of the separators stacked on both surfaces of the battery cells are stacked on each other at the bottom surfaces of the battery cells.
