Abstract
A bipolar secondary battery comprises laminated bodies. The laminated body comprises bipolar electrodes laminated via an electrolyte layer. The bipolar electrode comprises a positive electrode active material layer and a negative electrode active material layer formed on surfaces of a current collector. A positive electrode is formed on one end of the laminated bodies and a negative electrode is formed on another end. A temperature sensitive resistor having a smaller area than an electrical reaction area of the positive electrode active material layer and the negative electrode active material layer is arranged between the positive electrode and the negative electrode of a pair of adjacent laminated bodies, thereby suppressing a temperature increase caused by a high current by increasing the resistance in response to the flow of the high current into the bipolar secondary battery such as when an external circuit is shorted.
