Abstract
The present invention is aiming to provide a gas barrier film having excellent gas barrier properties and also having superior transparency and the like, and an efficient method for producing such a gas barrier film. The present invention provides a gas barrier film having a gas barrier layer on a base material, and a method for producing such a gas barrier film, in which the gas barrier layer includes, from the surface side toward the base material side, a first region and a second region having different refractive indices, the value of the refractive index in the first region is adjusted to a value within the range of 1.50 to 1.68, and the value of the refractive index in the second region is adjusted to a value within the range of 1.40 to below 1.50.
