1. A battery comprising:
a positive electrode current collector;
a positive electrode active material layer;
a solid electrolyte layer containing a solid electrolyte;
a negative electrode active material layer;
a negative electrode current collector; and
a sealing member,
wherein the battery has a structure in which the positive electrode current collector, the positive electrode active material layer, the solid electrolyte layer, the negative electrode active material layer, and the negative electrode current collector are laminated in this order,
wherein the battery has an opening hole penetrating the positive electrode current collector, the positive electrode active material layer, the solid electrolyte layer, the negative electrode active material layer, and the negative electrode current collector in a laminating direction of the structure,
wherein each of the negative electrode active material layer and the solid electrolyte layer has a laminating surface intersecting the laminating direction,
wherein, in cross-sectional view perpendicular to the laminating direction, the sealing member is located between the opening hole and each of the positive electrode active material layer, the solid electrolyte layer, and the negative electrode active material layer, and
wherein the sealing member is in contact with the positive electrode current collector and the negative electrode current collector and is in contact with a part of the laminating surface of the negative electrode active material layer or a part of the laminating surface of the solid electrolyte layer.
