PROBLEM TO BE SOLVED: To provide a transparent gas barrier laminate film configured to prevent gas barrier property from being deteriorated even when normally processed, and to exhibit excellent gas barrier property.SOLUTION: A gas barrier layer 2, and a gas barrier coating layer 3 are sequentially laminated on a surface of a base material layer 1. The gas barrier layer 2 is formed of silicon oxide. The gas barrier coating layer 3 is formed by coating and drying an application liquid containing at least one of a silicone compound represented by general formula Si(OR)and its hydrolysate, at least one of a silicon compound represented by general formula (RSi(OR))n and its hydrolysate, and an aqueous polymer having a hydroxyl group. A thickness (X) of the gas barrier layer 2 is 3-30 nm. A thickness (Y) of the gas barrier coating layer 3 is 50-3,000 nm. Arithmetic mean roughness Ra of a surface of the base material layer 1, on which the gas barrier layer 2 is laminated, is Z [nm], and a relationship of X, Y, and Z satisfies XY≥1,000, Z≤X/10. |
