Battery array configured to prevent vibration

The battery array is provided with a battery stack 5 having a plurality of rectangular battery cells 1 stacked together with intervening separators 2, endplates 3 disposed at the ends of the battery stack 5, and binding bars 4 extending in the battery cell 1 stacking direction and attached to the endplates 3 in a manner that binds both sides of the battery stack 5. The binding bars 4 are configured as plates of given width extending along the battery stack 5 surfaces. The binding bars 4 and separators 2 fit together in a linked configuration that limits their relative movement in the up-and-down direction.
