PROBLEM TO BE SOLVED: To provide a transparent gas barrier laminated film which can be suitably used in the case where gas barrier property is not deteriorated even if a usual processing is applied as a packaging material, and particularly where high gas barrier property is required in a packaging field such as food, daily commodities, and drug medicines or the field such as electronic apparatus related members. SOLUTION: The gas barrier laminated film is formed by successively laminating on one surface of a base layer 1 a gas barrier layer 2 (thickness Xa), a coated layer 3 (thickness Ya), a gas barrier layer 4 (thickness Xb), and a coated layer 5 (thickness Yb), and the relation among Xa, Xb, Ya, and Yb satisfies 0.002≤XaYa, 0.002≤XbYb, and XaYa+(Xa+Xb)Yb≤0.5 (unit:μm).
