PROBLEM TO BE SOLVED: To provide a gas barrier film having excellent oxygen barrier property under a high humidity condition, the gas barrier film having adhesive property between a sealant layer and a base material (gas barrier layer) when the sealant layer is laminated on the gas barrier layer.SOLUTION: A gas barrier film 100 includes a base material 10 and a gas barrier layer 11 at least on one face of the base material 10. The gas barrier layer 11 includes magnesium and silicon, and a mass ratio Mg/Si thereof is 0.3-0.65. The gas barrier film 100 includes the magnesium of 0.9 μg/cmor more, and the silicon of 1.7 μg/cmor more. The gas barrier layer 11 is preferably includes the magnesium of 5 μg/cmor less, the silicon of 9 μg/cmor less. |
