摘要：A substrate protective film composed of chromium metal is formed on amolding surface of a mold base material composed of cemented carbide. The substrateprotective film is oxidized by heat-treatment or ion implantation, so that a surface
protective film composed of chromium oxide is formed. A pair of molds having such aconstitution are prepared. Softened glass is pressed between the surface protective filmsof the paired molds, so that optical glass elements are molded.
