Claim:
1. A gas barrier film comprising: a base; a first gas barrier layer which is formed on the base by a physical vapor deposition method or a chemical vapor deposition method, wherein the first gas barrier layer is an inorganic film comprising silicon nitride or silicon oxynitride as a main component and has a film thickness of 40 nm or more and 200 nm or less; and a second gas barrier layer which is directly adjacent to the first gas barrier layer and is formed by coating a solution containing a polysilazane compound on the first gas barrier layer, wherein the second gas barrier layer has a film thickness of 50 nm or more and 300 nm or less, wherein the second gas barrier layer is subjected to a conversion treatment by being irradiated with a vacuum ultraviolet ray; and when the compositions of the second gas barrier layer is represented by SiO (A) the second gas barrier layer includes 50 nm or more of a region of 0.25≦x≦1.1 and 0.4≦y≦0.75 in the thickness direction.
