PROBLEM TO BE SOLVED: To provide a gas-barrier film having a strong gas-barrier layer at a temperature lower than a conventional temperature. SOLUTION: A method for producing a gas-barrier film by a method in which at least on one side of a base material, the gas-barrier film in which a layer containing a metal alkoxide expressed by formula r1x, R2y, R3z M(OR)m-(x+y+z) (R1, R2, R3 are each alkyl group or a hydrocarbon group having various functional groups; R is a general alkyl group; M is metal; m is the valence number of M; 0<=x,y,z<=3.0<x+y+z<m) or the ring opening reaction product of its hydrolysis product is installed and the layer containing the metal alkoxide or its hydrolysis product is installed at least on one side of the base material for producing the gas barrier film are formed, and electromagnetic waves are emitted in this process is provided.
