The first insulator includes a first electrolyte portion, a second electrolyte portion, and a first bent portion. The first bent portion is positioned between the first electrolyte portion and the second electrolyte portion. The first electrode layer is disposed in contact with the first electrolyte portion. The first counter-electrode layer is disposed in contact with the second electrolyte portion. The first insulator is bent at the first bent portion, and thereby the first electrode layer and the first counter-electrode layer are positioned facing each other.

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.

In plan view, the negative electrode active material layer is larger than the solid electrolyte layer. In plan view, each of the positive electrode current collector and the negative electrode current collector is larger than the negative electrode active material layer. In plan view, the sealing member is located outside the solid electrolyte layer. In cross-sectional view perpendicular to a laminating direction, the sealing member is disposed in a region sandwiched between a part of the positive electrode current collector and a part of the negative electrode active material layer and a region sandwiched between another part of the positive electrode current collector and a part of the negative electrode current collector.
