Abstract
A main object of the present disclosure is to provide a stacked battery in which an unevenness of short circuit resistance among a plurality of cells is suppressed. The present disclosure achieves the object by providing a stacked battery comprising: a plurality of cells in a thickness direction, wherein the plurality of cells are electrically connected in parallel; each of the plurality of cells includes a cathode current collector, a cathode active material layer, a solid electrolyte layer, an anode active material layer, and an anode current collector, in this order; the stacked battery includes a surface-side cell that is located on a surface side of the stacked battery, and a center-side cell that is located on a center side rather than the surface-side cell; and a contact resistance between the cathode current collector and the anode current collector in the surface-side cell is more than a contact resistance between the cathode current collector and the anode current collector in the center-side cell.
