PROBLEM TO BE SOLVED: To provide a gas barrier film having good barrier properties against oxygen or steam. SOLUTION: The gas barrier film comprises: a base material 2; the gas barrier layer 3 formed at least on one side of the base material 2 and comprising a vapor deposition film; and a sol-gel coating layer 4 formed on the gas barrier layer 3 and comprising a film containing a hydrolysate of an organometal compound or an alkali metal polysilicate represented by the formula: M<SB>2</SB>O-nSiO<SB>2</SB>(wherein M is lithium or a plurality of alkali metals containing lithium and n is a molar ratio of 1-20) and silica particles originating from colloidal silica.
