Power supply device includes a plurality of battery cells each having an exterior can in a prismatic shape, a pair of end plates having pressing surfaces that press both side end surfaces of battery stack in which the plurality of battery cells are stacked, a plurality of fastening members each of which has a plate shape extended in a stacking direction of the plurality of battery cells and is disposed on opposing side surfaces of battery stack to fasten end plates to each other, thermal plate for placing battery stack on an upper surface side to dissipate heat from battery stack, and heat transfer sheet interposed between an upper surface of thermal plate and a lower surface of battery stack to bring thermal plate and battery stack into a thermally coupled state. A part of a lower surface of each of end plates, the part facing heat transfer sheet, is disposed at the same height as or above an upper surface of heat transfer sheet.
