| description | A gas barrier film includes: a substrate; and a gas barrier layer located on at least one surface of the substrate, the gas barrier layer containing an aqueous polyurethane resin (A) that contains an acid group-containing polyurethane resin and a polyamine compound, a water soluble polymer (B), and an inorganic layered mineral (C), wherein, when a region from a top to a bottom of a cross-section of the gas barrier layer in a thickness direction, which is defined as a first region, is equally divided in the thickness direction into 11 strip regions, and a region different from the first region from a top to a bottom of a cross-section of the gas barrier layer in the thickness direction, which is defined as a second region, is equally divided in the thickness direction into 11 strip regions to thereby define a total of 22 strip regions; a portion having a length of 1 µm in a length direction perpendicular to the thickness direction in each of second, fourth, sixth, eighth, and tenth strip regions from a first surface of the gas barrier layer among the 11 strip regions in the first region, and a portion having a length of 1 µm in a length direction perpendicular to the thickness direction in each of second, fourth, sixth, eighth, and tenth strip regions from the first surface of the gas barrier layer among the 11 strip regions in the second region is each defined as a measurement target region to thereby select ten of the measurement target regions that constitute a first measurement target region group; a standard deviation of a luminance projection (α) in the length direction is obtained in each of the ten of the measurement target regions in the first measurement target region group; and an arithmetic mean of a plurality of the standard deviations of the ten of the luminance projections (α) in the first measurement target region group is obtained as an average, the average of the plurality of the standard deviations of the ten of the luminance projections (α) in the first measurement target region group in the gas barrier layer is 10 or less. |
