A bipolar battery (1) of the present invention includes a battery element (10) composed by stacking in series a plurality of bipolar electrodes (11), in each of which a positive electrode is formed on one surface of a collector and a negative electrode is formed on the other surface, with electrolytes (14) interposed therebetween. Further, the bipolar battery includes laminate films (20) covering the battery element (10), each of the laminate films (20) containing a metal layer (21), and tabs (30) composed by being extracted from the battery element (10) to outsides of the laminate films (20). In the bipolar battery, thickness of a resin layer (23a) interposed between the tab (30) and the metal layer (21) is equal to or more than thickness of the tab (30). |
