The present invention relates to a gas barrier film which has improved adhesiveness between a base material and a barrier laminate. In the gas barrier film, a plastic film, an organic layer, and an inorganic layer are provided in this order. Between the plastic film and the organic layer, there is a silicon compound layer including at least one compound selected from a group consisting of silicon oxide, silicon nitride, and silicon carbide. The plastic film and the silicon compound layer and the silicon compound layer and the organic layer are adjacent to each other. The silicon compound layer has a film thickness of 40 nm or less. The organic layer is formed from a composition containing a polymer compound and a silane coupling agent.
