An object of this invention is to provide the manufacturing method of the gas barrier property film which is applicable also to the manufacturing process of a roll-to-roll system, has high gas barrier property, and is excellent in storage stability. The present invention relates to a method for producing a gas barrier film, which is carried out by continuously conveying a substrate, wherein a coating liquid containing a polysilazane compound is applied to at least one surface of the substrate to form a coating film. Gas barrier properties having a film forming step, at least two vacuum ultraviolet ray irradiation steps for irradiating the coating film with vacuum ultraviolet rays, and at least one oxidation step between the at least two vacuum ultraviolet ray irradiation steps It is a manufacturing method of a film. |
