PROBLEM TO BE SOLVED: To provide a transparent gas barrier laminated film not lowered in its gas barrier properties even if various post-processings such as printing, lamination, bag making and the like are applied. SOLUTION: In the gas barrier laminated film constituted by laminating a vapor deposition thin film layer comprising aluminum oxide or the like and at least two gas barrier film layers, of which the total thickness of 0.02-20μm, on one side of a base material layer, at least two gas barrier film layers are constituted by laminating at least two uncured flash vapor deposition film layers, each of which comprises an acrylic monomer containing at least one of a monoacrylate, a diacrylate and a triacrylate or a mixture of the monomer and an oligomer and subsequently irradiating both layers with ultraviolet rays or an electron beam to cure them at the same time. The viscosity of the monomer or the mixture is 200 mPa s/25°C and the surface of the vapor deposition film layers and/or the outermost surface of the gas barrier film layers is subjected to plasma treatment.
