Abstract
A positive-electrode bodyis prepared that includes a positive-electrode active-material layerincluding a powder-molded body, and a positive-electrode-side solid-electrolyte layer (PSE layer)that is amorphous and formed on the positive-electrode active-material layerby a vapor-phase process. A negative-electrode bodyis prepared that includes a negative-electrode active-material layerincluding a powder-molded body, and a negative-electrode-side solid-electrolyte layer (NSE layer)that is amorphous and formed on the negative-electrode active-material layerby a vapor-phase process. The positive-electrode bodyand the negative-electrode bodyare bonded together by subjecting the electrode bodiesandbeing arranged such that the solid-electrolyte layersandof the electrode bodiesandare in contact with each other, to a heat treatment under application of a pressure to crystallize the PSE layerand the NSE layer
