STACKED BATTERY

To suppress heat generation in a stacked battery including a plurality of electric elements in internal short circuits and an unstable reaction when the battery is operated while an energy level is increased, the stacked battery includes a stack, wherein the stack comprises a first current collector layer that composes one end face in a stacking direction of the stack, a second current collector layer that composes another end face in the stacking direction, a plurality of bipolar current collector layers that are arranged between the first and second current collector layers at intervals in the stacking direction, and a plurality of electric elements that are electrically connected to each other in series via the bipolar current collector layers between the first and second current collector layers, each of the electric elements comprises a cathode active material layer, an anode active material layer, and an electrolyte layer that is arranged between the cathode and anode active material layers, and the ratio h/S (cm) of a length h (cm) between the one end face and the other end face in the stacking direction of the stack to an electrode area S (cm) on a cross section orthogonal to the stacking direction of the stack is more than 1.
