Stacked battery, assembled battery and vehicle

A stacked battery comprises a sheet electrode including a collector, and an electrolyte layer placed between the electrodes. In the stacked battery, an electrode stacked body is formed by stacking the electrode and the electrolyte layer, and the electrodes are placed on outermost layers of the electrode stacked body in such a manner so that the collectors are exposed to the outside of the stacked battery in the stacking direction of the electrode stacked body and function as terminals.
