An object of the present invention is to provide a transparent barrier film that has excellent acid resistance and is inexpensive, and a method for producing the same. A transparent gas barrier film includes a plastic film and an aluminum oxide layer provided on at least one surface of the plastic film, the aluminum oxide layer mainly composed of aluminum oxide. The absorption coefficient of the inorganic oxide layer immediately after vapor-deposition is less than 0.03 nm−1, and the film thickness of the inorganic oxide layer is 6 nm or more and 10 nm or less.
