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.
