Abstract: When a bipolar battery is manufactured, a bipolar electrode and a separator are prepared first. Then, one electrode (for example, a positive electrode) out of positive and negative electrodes is applied with such an amount of electrolyte as being exposed on a surface of the one electrode. Then, the separator is arranged on the surface of the one electrode applied with the electrolyte, thus forming a sub-assembly unit. Then, a plurality of the sub-assembly units are layered, and the electrolyte applied to the one electrode is made to permeate through the separator to the other electrode, thus forming an assembly unit.
