Abstract: A laminated battery includes battery cells which are laminated and a current collecting lead. Each of the battery cells has a structure in which a positive electrode current collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector are laminated in this order. The battery cells include first and second battery cells adjacent to each other. At least the second battery cell has a side surface inclined with respect to a laminating direction of the battery cells. The first battery cell has a surface facing the second battery cell and including an exposed surface not in contact with the second battery cell. At least part of the exposed surface overlaps at least part of the side surface of the second battery cell viewed from the laminating direction. The current collecting lead is connected to the exposed surface.

Abstract: A battery includes an electrode layer, a counter electrode layer, which is a counter electrode for the 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 positioned within a region where the electrode layer and the counter electrode layer face each other. 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. The first region includes a first projecting portion that projects outward from a region where the electrode layer and the counter electrode layer face each other, and the second region covers the first projecting portion.
