PROBLEM TO BE SOLVED: To provide a gas barrier film which can suppress deterioration of gas barrier properties sufficiently even when exposed to long-time continuous vibration.SOLUTION: A gas barrier film includes a substrate 1 and one or more gas barrier layers 3 formed on at least one surface of the substrate 1, and at least one of the gas barrier layers 3 contains silicon, oxygen and nitrogen. Among distribution curves of individual constituent elements for the gas barrier layers 3 based on element distribution measurement in the depth direction by X-ray photoelectron spectroscopy, a nitrogen distribution curve C representing the relationship of the distance from the surface of a gas barrier layer 3 in the layer thickness direction of the gas barrier layer 3 and the ratio of the amount of nitrogen atoms to the total amount (100 at%) of silicon, oxygen and nitrogen atoms (nitrogen atomic ratio (at%)) has at least one extreme value. |
