Abstract: A solid-state battery includes a multi-layer body, a silica-based glass material, and buffer layers. The multi-layer body includes a positive electrode layer and negative electrode layers, all of which are electrode layers, and includes solid electrolyte layers. The electrode layers and the solid electrolyte layer are alternately stacked, and for example, two of the negative electrode layers are located as the outermost layers. The silica-based glass material covers the multi-layer body. The buffer layers have an insulating property, and are formed between the outermost negative electrode layers of the multi-layer body and the silica-based glass material.
