Abstract

A stacked battery sealed by a film casing shows a raised degree of resistance against vibrations. The stacked battery includes a stacked body formed by alternately laying plate-like positive electrodes and plate-like negative electrodes one on the other by way of separators, each of the positive electrodes and the negative electrodes having recessed sections and corresponding projecting sections, the recessed sections of each electrode being disposed vis-a-vis the projecting sections of one of the adjacent electrodes of the opposite polarity and the projecting sections of each electrode being disposed vis-a-vis the recessed sections of the other adjacent electrode of the opposite polarity except the those arranged closest to the exposed surfaces of the stacked body, and holding members respectively engaged directly or through at least one of the separator and the film casing with the recessed sections and the projecting sections of the electrodes arranged closest to the exposed surfaces, the holding members being rigidly secured to the film casing covering the stacked body and sealing the stacked battery, the positive electrodes and the negative electrodes being respectively connected to a positive terminal and a negative terminal.
