PROBLEM TO BE SOLVED: To provide a gas barrier film of an organic-inorganic lamination type assuring low water vapor permeability and good inter-layer tight attaching performance. SOLUTION: The gas barrier film having a barrier layer containing an organic layer and an inorganic layer at least on one surface of a plastic film, wherein the barrier layer is composed of the organic layer, a first inorganic layer having a film density of 1.7 or more, and a second inorganic layer whose film density is 0.5-1.5 higher than the first inorganic layer.
