The upper open ends of the plurality of prismatic cell cases are integrally closed by a single lid member. Each of the cells accommodates therein a group of electrodes stacked alternately upon one another parallel to the long lateral walls of the cell cases with intervening separators therebetween. Neighboring cells are connected in series at their abutting lateral opposite ends with each other.
