Abstract
A bipolar battery includes: a power generation element formed by stacking a plurality of bipolar electrodes, in which an electrode layer is formed on a front and a rear of a collector, via an electrolyte layer; an elastic metal portion provided in contact with the power generation element so as to contact the power generation element in point or line contact when no external force is exerted thereon and contact the power generation element in surface contact when external force is exerted thereon; and an outer covering material provided to accommodate the power generation element and the elastic metal portion, an internal air pressure of which is set to be lower than an atmospheric pressure such that the elastic metal portion is caused to contact the power generation element in surface contact by a pressure difference between the internal air pressure and the atmospheric pressure.
