PROBLEM TO BE SOLVED: To provide a gas barrier film which ensures high productivity and has compatibility between barrier property and transparency. SOLUTION: Disclosed is the transparent barrier film having a silicon oxide layer formed on a transparent base film, wherein the silicon oxide layer comprises two layers of a first layer and a second layer in order from the transparent base film side, and the refractive index and the film thickness of respective layers has following relations, the refractive index: n1>n2; the film thickness: t1<t2, and t1+t2<100, wherein, n1:the refractive index of the first layer, n2: the refractive index of the second layer, t1:the film thickness (unit:nm) of the first layer, and t2: the film thickness (unit:nm) of the second layer.
