Provided is a power supply device that is configured to dispose each of battery cells at an ideal position while stacking the battery cells to form a battery stack, the power supply device including: battery cells (1) each having an outer covering can in a prismatic shape and having a constant cell thickness; end plates paired for covering both side end surfaces of the battery stack in which battery cells (1) are stacked; and bind bars (15) that are disposed on opposite side surfaces of the battery stack and coupled to the end plates. Bind bar (15) includes pressing piece (151) for pressing an upper surface of each of battery cells (1) adjacent to each other. The power supply device further includes elastomer molding (18) disposed between pressing piece (151) and an upper surface of battery cell (1), and pressing piece (151) elastically presses the upper surface of battery cell (1) with elastomer molding (18).
