PROBLEM TO BE SOLVED: To provide a method for producing an optical recording medium by which generation of camber can be prevented. SOLUTION: In a first substrate molding process 51, a first substrate is molded by injection molding of a light transmissive resin. In a reflecting film forming process 52, a reflecting film is formed on the first substrate. In a substrate inverting process 53, the first substrate on one surface of which the reflecting film is formed is inverted in a sputtering device. In a moisture-proof film forming process 54, a moisture-proof film is formed on another surface of the first substrate. In a second substrate molding process 55, a second substrate is molded by injection molding similar as the first substrate molding process 51. In a semitransparent reflecting film forming process 56, a semitransparent reflecting film is formed on the second substrate. In the substrate inverting process 57, the second substrate on one surface of which the semitransparent reflecting film is formed is inverted in the sputtering device. In the moisture-proof film forming process 58, the moisture-proof film is formed on another surface of the second substrate. In a sticking process 59, the first substrate and the second substrate are stuck. In a protective film forming process 60, a protective film is formed on the reflecting film of the first substrate. |
