Beschreibung
Zusammenfassung:	A bipolar battery includes a plurality of cell members and a plurality of frame units configured to form a plurality of cells individually housing the plurality of cell members. Each of the plurality of frame units has joining surfaces facing each other in the stacking direction of the cell members, which are joined to each other by a joining material. On outer side surfaces of the frame units adjacent to each other in the stacking direction, a groove is formed which communicates between the joining surfaces to be joined and opens to the outer side surfaces. A water sealing material is disposed in the groove. This arrangement provides a bipolar battery capable of reliably preventing an electrolyte from leaking out of a cell by a simple seal configuration.
