Provided is a bipolar battery (1) comprising: a power generation element (10) in which a plurality of bipolar electrodes (11) obtained by forming electrode layers (112, 113) on the front and back of a collector (111), are stacked with electrolyte layers (12) interposed therebetween; an elastic metal part (21) provided so as to be in contact with the power generation element (10), to be in point or linear contact with the power generation element (10) when external force is not applied, and to be in surface contact with the power generation element (10) when external force is applied; and a casing (30) that is provided so as to accommodate the power generation element (10) and the elastic metal part (21), is kept at an internal pressure below the atmospheric pressure, and causes the elastic metal part (21) to be brought into surface contact with the power generation element (10) by the pressure difference between the internal pressure and atmospheric pressure. |
