PROBLEM TO BE SOLVED: To provide a bipolar battery capable of preventing or suppressing performance degradation occurred at a time of overcharge of an electric cell of a bipolar battery.SOLUTION: The bipolar battery is formed by laminating a bipolar electrode formed by forming a positive electrode active material layer 2 on one surface of a collector and forming a negative electrode active material layer 3 by sandwiching a solid electrolyte layer 4. A ratio of negative electrode capacity to positive electrode capacity is smaller than 1. The solid electrolyte layer includes a through-hole 5. |
