A bipolar secondary battery is provided with an electric power generating unit, a pair of terminal plates. The electric power generating unit includes a plurality of bipolar electrodes stacked on one another with an electrolyte layer disposed between the bipolar electrodes and separating the bipolar electrodes. Each of the bipolar electrodes includes a collector with a positive electrode active material layer formed on a first side surface of the collector, and a negative electrode active material layer formed on a second side surface of the collector. The first terminal plate is connected to a first stacking direction facing end of the electric power generating unit. The second terminal plate is connected to a second stacking direction facing end of the electric power generating unit. At least one of the terminal plates includes an electric current suppressing device that suppresses an electric current occurring when an internal short circuit occurs in the electric power generating unit.
