A bipolar secondary battery includes a power generating element in which a bipolar electrode and an electrolyte layer are stacked. The bipolar electrode includes a positive-electrode active material layer formed on one surface of a current collector and a negative-electrode active material layer formed on the opposing surface of the current collector. Peripheral edges of the bipolar electrode and electrolyte layer are bonded through a seal. Edges of the positive-electrode active material layer and the negative-electrode active material layer on opposite surfaces of a respective current collector are offset from each other. The edge of a seal portion facing an inner edge of the edges of the positive-electrode active material layer and the negative-electrode active material layer is positioned inside an outer edge of the edges of the positive-electrode active material layer and the negative-electrode active material layer.
