PROBLEM TO BE SOLVED: To provide a gas barrier laminated film excellent in the gas barrier properties against oxygen and steam, having transparency, flexibility, humidity resistance and heat resistance and easy to manufacture. SOLUTION: The gas barrier laminated film is constituted by laminating a coating layer, which contains a polyvinyl alcohol polymer as an essential component and is characterized in that the water contact angle of the coating layer is 30°or above, on a base material comprising a high-molecular resin composition and laminating an inorganic thin film layer on the coating layer containing the polyvinyl alcohol polymer as the essential component.
