Abstract: A gas barrier film includes a base film including a plastic material, and one or more gas barrier layers formed on the base film. The gas barrier layer includes an inorganic layered mineral and a resin component interposed between layers of the inorganic layered mineral. The gas barrier film shows an X-ray diffraction spectrum having a first peak top and a second peak top when measured at 25° C. and 65% RH using CuKα rays, the first peak top is derived from a first interlayer distance between adjacent layers of the inorganic layered mineral, the second peak top is derived from a second interlayer distance which is greater than the first interlayer distance by interposition of the resin component between layers of the inorganic layered mineral, and the second peak top is present at a position lower than a position of the first peak top in a 2θ axis.
