PROBLEM TO BE SOLVED: To provide a gas barrier laminated film having high-degree gas barrier functionalities. SOLUTION: A vapor deposition film 2 comprising a first inorganic oxide overlies one side of a base material film 1. Further, a first gas barrier coating film 3, 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 first inorganic oxide, and a vapor deposition film 4 comprising a second inorganic oxide and a second gas barrier coating film 5 further successively overlie the first gas barrier coating film 3 in the same way to obtain the gas barrier laminated film A.
