PROBLEM TO BE SOLVED: To provide a gas barrier film which has sufficient gas barrier properties even in a high-temperature, high-humidity service environment, is suppressed in deterioration of gas barrier properties even when the film is bent and also is excellent in crack resistance.SOLUTION: A gas barrier film 1a has a gas barrier layer 3 containing silicon and oxygen on at least one side of a substrate 1. In the oxygen distribution curve based on element distribution measurement of the gas barrier layer 3 in the depth direction by X-ray photoelectron spectroscopy, a peak of the oxygen distribution curve closest to the surface of the gas barrier layer 3 on the side of the substrate 1 is the largest value among maximum values of the oxygen distribution curves in the gas barrier layer 3. |
