    • PROBLEM TO BE SOLVED: To provide a method for producing a silicon nitride film superior in a gas barrier property, at a low temperature.
      SOLUTION: The method for producing the silicon nitride film comprises: a decompression step of decompressing the inside of a vacuum chamber 2 into a vacuum state, which has a plastic film 15 arranged on a coolable substrate holder 4 and a heatable tungsten wire 6 arranged above the plastic film 15 therein, with a pressure reducing device 3; a gas introduction step of introducing a silane gas, ammonia gas and hydrogen gas into the vacuum chamber 2 which has been decompressed in the decompression step, with a shower head 5; a gas decomposition step of contacting the gases introduced into the vacuum chamber 2 in the gas introduction step, with the tungsten wire 6 while heating the tungsten wire 6, to decompose the gases; and a film-forming step of forming the silicon nitride film on the surface of the plastic film 15, by depositing the decomposed species of the gas obtained in the gas decomposition step, on the surface of the plastic film 15 while cooling the substrate holder 4.
