    Abstract: A main object of the present disclosure is to provide a stacked battery in which sneak current caused by an unevenness of a 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 with a cathode current collecting tab, a cathode active material layer, a solid electrolyte layer, an anode active material layer, and an anode current collector with an anode current collecting tab, 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 the surface-side cell and the center-side cell satisfy at least one of: condition i) a resistance of the cathode current collecting tab in the surface-side cell is more than a resistance of the cathode current collecting tab in the center-side cell; and condition ii) a resistance of the anode current collecting tab in the surface-side cell is more than a resistance of the anode current collecting tab in the center-side cell.
