Abstract
A battery main body housed in a case comprises one laminated body composed of a plurality of bipolar electrodes laminated with an electrolyte layer therebetween or comprises a plurality of laminated bodies connected in series. A positive electrode current collecting plate and a negative electrode current collecting plate each having one surface joined to the inner peripheral surface of the case and the other surface joined to one end of the battery main body respectively extend to the outside of the case. By providing a cutoff mechanism for cutting off an electrical connection between the positive electrode current collecting plate and the negative electrode current collecting plate via the battery main body according to an expansion deformation of the case, a current path in a bipolar secondary battery is interrupted when the short-circuit current occurs, thereby protecting the bipolar secondary battery from a short-circuit current.
