PROBLEM TO BE SOLVED: To provide a gas barrier film capable of exhibiting a high light transmissivity while maintaining high gas barrier capacities against water vapor, etc.SOLUTION: The provided gas barrier film 10 comprises: a substrate 1 formed by a transparent resin; an undercoat layer 2 formed atop the substrate 1 by a fluorene-based acrylate including, among constituent units, a hydroxy group-free oxyalkylene group and a fluorene group; an inorganic deposition layer 3 formed atop the undercoat layer 2 by silicon oxide SiOx (1.7≤x≤2.2); and an overcoat layer 4 formed atop the inorganic deposition layer 3 by a metal alkoxide and a water-soluble polymer in a state where the film thickness thereof is being confined to a range of 250 nm to 500 nm. |
