Abstract: A laminated battery includes battery cells which are laminated and a current collecting lead. Each of the battery cells has a structure in which a positive electrode current collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector are laminated in this order. 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.

Abstract: A battery is provided which includes a first power generating element, a second power generating element, and a first adhesion layer adhering the first power generating element to the second power generating element. A first positive electrode collector of the first power generating element and a second negative electrode collector of the second power generating element face each other with (i.e., via) the first adhesion layer. Between the first positive electrode collector and the second negative electrode collector, the first adhesion layer is disposed in a region forming a first positive electrode active material layer or a region forming a second negative electrode active material layer, whichever is smaller. The first positive electrode collector and the second negative electrode collector are not in contact with each other in a region in which the first positive electrode active material layer and the second negative electrode active material layer face each other.
