PROBLEM TO BE SOLVED: To provide a gas barrier laminated film excellent in gas barrier properties and winding-up appearance. SOLUTION: A biaxially stretched polyamide film with a coefficient of dynamic friction of 0.4 or below, haze of 6.0% or below, an ash test performance of 15 mm or below and surface roughness of at least one surface of the film of 2,000 nm or below is used as a base material film 10, and the gas barrier laminated film is constituted by providing a vapor deposition film 20 of an inorganic oxide on the surface of the base material film with the surface roughness of 2,000 nm or below and providing a predetermined gas barrier coating film 30 on the surface of the vapor deposition film 20 of the inorganic oxide. This gas barrier laminated film is excellent in gas barrier properties, transparency, slip properties and winding-up appearance. COPYRIGHT: (C)2008,JPO&INPIT
