A photoelectric conversion device in which a thin crystalline Pb--Cr oxide film is formed on the surface of a substrate and a pair of spaced apart conductive film electrodes are formed on the thin film. The thin crystalline Pb--Cr oxide film is formed by a vacuum evaporation process using a sintered body prepared from PbO and Cr.sub.2 O.sub.3 as a target and heat treating the thin film in an atmosphere containing Pb.
