[Problem] To provide a means whereby gas barrier capabilities, and endurance of gas barrier capabilities, of a gas barrier film may be further improved. [Solution] A gas barrier film having: a base material; a first barrier layer situated on at least one surface of the base material, having a film density of 1.5-2.1 c/m 3 , and containing an inorganic compound; and a second barrier layer formed on the surface of the base material on the same side where the first barrier layer is formed, and containing silicon atoms, oxygen atoms, and at least one added element from the group consisting of elements of Groups 2-14 of the long form of the periodic table (excluding silicon and carbon), the ratio (O/Si) of oxygen atoms to carbon atoms being 1.4-2.2, and the ratio (N/Si) of nitrogen atoms to carbon atoms being 0-0.4. |
