Provided is a method for producing a gas barrier plastic molded body by forming a gas barrier thin film which is substantially colorless and has gas barrier properties, on the surface of a plastic molded body by a heating element CVD method using only raw material gases that are highly safe. The method for producing a gas barrier plastic molded body according to the present invention is a method for producing a gas barrier plastic molded body ( 90 ) by forming a gas barrier thin film ( 92 ) on the surface of a plastic molded body ( 91 ), the method comprising: a film-forming process in which the gas barrier thin film ( 92 ) is formed on the surface of the plastic molded body by a heating element CVD method, using an organosilane-based compound represented by formula (Chemical Formula 1) as a main raw material gas, using an oxidizing gas as an additive gas, and using a heating element containing tantalum (Ta) as a main constituent element:n nH 3 Si—Cn—X (Chemical Formula 1)n nwherein in Chemical Formula 1, n represents 2 or 3; and X represents SiH 3 , H, or NH 2 . |
