A method of forming a vapor-deposited film by holding a substrate to be treated in a plasma processing chamber, and supplying an organosilicon compound and an oxidizing gas into the processing chamber to perform chemical plasma treatment to form a silicon oxide on the surface of a substrate. In this method, the vapor-deposited film is formed by maintaining a constant supply amount of the organosilicon compound gas in the plasma processing chamber and changing the supply amount of the oxidizing gas during the film-forming process for preparing the vapor-deposited film. It is a chemical vapor deposition film with excellent compatibility, flexibility, flexibility, oxygen barrier properties and moisture barrier properties.
