In order to reliably prevent displacement of battery cells while a bottom surface of a battery stack is exposed over an entire width, in a power supply device, a pair of end plates (3) are disposed at both end surfaces of a battery stack (2) in which the plurality of battery cells (1) are stacked, end plates (3) are coupled to a bind bar (4), the battery stack (2) is sandwiched between the end plates (3) to be held, an elastic sheet (6) that is elastically deformable in a thickness direction is disposed in a compressed state between the bind bar (4) and a facing side surface (2C) of the battery stack (2), and the elastic sheet (6) in the compressed state elastically holds the battery stack (2) and the bind bar (4) in a pressurized state.
