NOVELTY - Bipolar secondary battery comprises electric power generating unit including bipolar electrodes, where bipolar electrodes including collector, positive and negative electrode active material layer; and pair of terminal plates (101, 102) with first and second terminal plate connected to first and second stacking direction facing end of electric power generating unit, respectively.    USE - The bipolar secondary battery used in battery pack; and as electric power source in vehicle (claimed).    ADVANTAGE - The bipolar secondary battery prevents an occurrence of concentration of current in a terminal plate caused by an internal short circuit in the bipolar secondary battery; is utilized as a technology for improving the reliability of bipolar secondary batteries.    DETAILED DESCRIPTION - A bipolar secondary battery comprises an electric power generating unit including several of bipolar electrodes stacked on one another in a stacking direction with an electrolyte layer disposed between the bipolar electrodes and separating the bipolar electrodes, where each of bipolar electrodes including collector, positive electrode active material layer formed on first side surface of the collector, and negative electrode active material layer formed on second side surface of the collector; and a pair of terminal plates (101, 102) with a first terminal plate connected to a first stacking direction facing end of the electric power generating unit and a second terminal plate connected to a second stacking direction facing end of the electric power generating unit, where at least one of first and second terminal plates including an electric current suppressing device that suppresses an electric current occurring when an internal short circuit occurs in the electric power generating unit.
