Provided is a gas barrier film having excellent barrier properties against oxygen and water vapor, etc., and particularly having high water vapor barrier properties. The gas barrier film is a film comprising an inorganic compound thin film formed on at least one surface of a plastic film, and is characterized by the inorganic compound thin film containing as the main components thereof aluminum oxide and magnesium oxide. Ideally the magnesium oxide ratio to 100% by mass aluminum oxide and magnesium oxide included in the inorganic compound thin film is 5%-90% by mass, and it is desirable that the film thickness of the inorganic compound thin film is 5-500 nm. |
