In order to provide a power supply device or the like having end plates that can maintain restraint of secondary battery cells while partially allowing deformation, the power supply device includes: a plurality of secondary battery cells; a pair of end plates (3) disposed on end surfaces of a battery stack obtained by connecting the plurality of secondary battery cells to sandwich the battery stack; and a fastening member for fixing the end plates (3) to each other. The end plate (3) includes a first band body (31) protruding from a main surface of the end plate (3) on an upper end side of the end plate (3) and second a band body (32) protruding from the main surface of the end plate (3) in a middle of the end plate (3). A space (32a) is formed in the second band body (32) between the second band body (32) and the main surface of the end plate (3).
