A laminated battery includes a plurality of battery cells which are laminated and a current collecting lead. Each of the plurality of battery cells includes a positive electrode current collector, a solid electrolyte layer, a positive electrode active material layer disposed between the positive electrode current collector and the solid electrolyte layer, a negative electrode current collector, and a negative electrode active material disposed between the positive electrode active material and the negative electrode current collector. The plurality of battery cells include a first battery cell and a second battery cell that are adjacent to each other. The first battery cell has a surface facing the second battery cell. The surface facing the second battery cell includes an exposed surface that is not in contact with the second battery cell. At least part of the exposed surface does not overlap the second battery cell when viewed from a laminating direction of the plurality of battery cells. The current collecting lead is connected to the exposed surface.
