Abstract
A gas barrier film includes a resin film base material, a layer made of an aqueous coating agent (A) which contains a hardener and has gas barrier properties and adhesiveness to the resin film base material, the layer made of the aqueous coating agent (A) being formed on at least one surface of the resin film base material, and at least one layer made of an aqueous coating agent (B) having a compounding ratio of a hardener smaller than that of the aqueous coating agent (A), the layer made of the aqueous coating agent (B) being formed on the layer made of the aqueous coating agent (A).
