Abstract
A battery includes a positive electrode current collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, a negative electrode current collector, and a sealing member. 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.
