Abstract
A silicon oxide film is formed on the surfaces of a plastic substrate and contains methyl groups and methylene groups in a portion near the interface to the plastic substrate. The silicon oxide film exhibits not only excellent adhesion to the plastic substrate, softness and flexibility but also exhibits excellent gas shut-off property (gas barrier property), makes it possible to achieve excellent gas-shutoff property with a smaller film thickness than that of the conventional films, and can be mass-produced favorably.
