The production method for this solid-state battery 100, which contains a positive electrode 110, a solid electrolyte 120, and a negative electrode 140, comprises the steps of: preparing a negative electrode 140 that is free of a negative-electrode active material; and forming, on at least one surface of the negative electrode 140, a solid electrolyte interface layer 130 including a lithium-containing organic compound and a lithium-containing inorganic compound by immersing the negative electrode 140 in a layer forming solution containing a lithium salt and a precursor and thereafter causing a reduction reaction on the surface of the negative electrode 140.",
