PROBLEM TO BE SOLVED: To provide a transparent gas barrier laminated film superior in oxygen barrier properties and steam barrier properties. SOLUTION: In the gas barrier laminated film constituted by successively laminating a gas barrier layer 2 and a coating film layer 3 on at least on one side of a base material layer 1 comprising a transparent plastic film, the gas barrier layer 2 comprises silicon oxide and has a film thickness (thickness X) of 0.005-0.2μm, while the coating film layer 3 is formed by forming a mixture of a polymerizable acrylic monomer or a mixture of the monomer and an oligomer into a film by a flash vapor deposition method and irradiating the formed film with ultraviolet rays or an electron beam to cure the same. The film thickness (thickness Y) of the coating film layer 3 is 0.1-20μm and the relation between the thickness X of the gas barrier layer 2 and the thickness Y of the coating film layer 3 satisfies the formula: 0.002≤XY≤0.5 (wherein the units of X and Y areμm).
