PROBLEM TO BE SOLVED: To provide a gas barrier laminated film having high-degree gas barrier functionalities. SOLUTION: The gas barrier laminated film comprises as follows. A vapor deposition film comprising an inorganic oxide overlies one side of a base material film. Further, a gas barrier coating film, which comprises a gas barrier composition containing at least one kind of an alkoxide represented by the general formula: R<SP>1</SP><SB>n</SB>M(OR<SP>2</SP>)<SB>m</SB>(wherein the meanings of R<SP>1</SP>, R<SP>2</SP>, M, n, m and n+m are abbreviated), scaly silicon dioxide particles and a polyvinyl alcohol resin and/or an ethylene/vinyl alcohol copolymer and obtained by the polycondensation due to a sol-gel method, overlies the vapor deposition film comprising the inorganic oxide.
