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 battery cells include first and second battery cells adjacent to each other. At least the second battery cell has a side surface inclined with respect to a laminating direction of the battery cells. The first battery cell has a surface facing the second battery cell and including an exposed surface not in contact with the second battery cell. At least part of the exposed surface overlaps at least part of the side surface of the second battery cell viewed from the laminating direction. The current collecting lead is connected to the exposed surface.
