In the module battery, by disposing end plates including a flat plate portion and a rectangular frame portion at each end of a cell group and by binding the cell group by means of binding members and metal studs, the increase of the internal pressure during the charging/discharging cycles and the dimensional change of the module battery due to the expansion of the cell group can be suppressed, while the weight and volume increase caused by the binding members is minimized.
