Abstract
A power supply device includes: a battery stack body that includes a plurality of secondary battery cells that are stacked; a pair of end plates disposed on both end surfaces of the battery stack body, respectively; and binding bars that are disposed on both the end surfaces of the battery stack body, respectively, and bind the pair of end plates. Each of the binding bars includes engaging steps that are opposite the pair of end plates, respectively. Each of the engaging steps extends in a direction intersecting with a stack direction of the battery stack body. Each of the pair of end plates includes engaging protrusions that are opposite the binding bars, respectively. The engaging protrusions engage with engaging steps. Consequently, rigidity that binds the battery stack body together is increased without changing a material and a thickness of the binding bars.
