Abstract: A battery includes an electrode layer, a counter electrode layer, and a solid electrolyte layer between the electrode layer and the counter electrode layer. The solid electrolyte layer has a first region containing a first solid electrolyte material and a second region containing a second solid electrolyte material. The first region is within a region where the electrode layer and the counter electrode layer face each other. With respect to the first region, the second region is positioned on an outer peripheral side of the region where the electrode layer and the counter electrode layer face each other, and is in contact with the first region. A second density, which is the density of the second solid electrolyte material in the second region, is higher than a first density, which is the density of the first solid electrolyte material in the first region.
