A power supply device is provided with: a battery block (10) in which a plurality of battery cells (1) are laminated in the thickness direction with a separator (2) therebetween; a pair of end plates (3) disposed on both end surfaces of the battery block (10); and a lacing strip (4) that is connected to the pair of end plates (3) and that fixes the battery block (10) in a pressurized state by means of the end plates (3). The separator (2) is an elastic body, and both surfaces of a plate-shaped portion (20) of the separator (2) are formed as uneven layers (25) having different amounts of change in thickness with respect to pressing force.
