In power supply device, binding bar is fixed to a pair of end plates disposed at both ends of battery stack formed by stacking a plurality of battery cells in order to suppress displacement of the battery cells by reducing deformation of the battery stack. Binding bar is provided with fixing piece of bracket fixed to base plate so as to protrude from a surface of binding bar. In binding bar, an middle part of the binding bar is defined as a fixing piece region, a straight part extending in a longitudinal direction at a part of an outer peripheral edge is defined as a bending line, a region excluding the bending line is cut along a cutting line and bent along the bending line, the fixing piece region is defined as fixing piece protruding outward, and fixing piece region is defined as opening window. Bracket includes a fixing part, rising part, and base plate connector, fixing piece is fixed to the fixing part, and binding bar is fixed to base plate via bracket.
