Abstract:
1. A gas-barrier multilayer film comprising: a base member; and at least one thin film layer formed on at least one surface of the base member, wherein at least one layer of the thin film layer(s) satisfies the following requirement (A): [Requirement (A)] the layer contains silicon, oxygen, and carbon, and in a silicon distribution curve, an oxygen distribution curve, and a carbon distribution curve all the following requirements (i) to (iii) are satisfied, each of the silicon distribution curve, the oxygen distribution curve, and the carbon distribution curve representing the relationship between the distance from a surface of the layer in the film thickness direction of the layer and corresponding one of the ratio of the amount of silicon atoms to the total amount of silicon atoms, oxygen atoms, and carbon atoms (the atomic ratio of silicon), the ratio of the amount of oxygen atoms to said total amount (the atomic ratio of oxygen), and the ratio of the amount of carbon atoms to said total amount (the atomic ratio of carbon): wherein the at least one extremum of the carbon distribution curve is a local maximum or a local minimum of the atomic ratio of carbon with respect to the distance from a surface of the thin film layer in the film thickness direction of the thin film layer, the local maximum is a point at which change of the value of the atomic ratio of carbon turns from increase to decrease when the distance from the surface of the thin film layer is changed and the value of the atomic ratio of carbon decreases by 3 at % or more in comparison to the value of the atomic ratio of carbon at a point when the distance from the surface of the thin film layer in the film thickness direction of the thin film layer is further changed by 20 nm, and the local minimum is a point at which the change of the value of the atomic ratio of carbon turns from decrease to increase when the distance from the surface of the thin film layer is changed and the value of the atomic ratio of carbon increases by 3 at % or more in comparison to the value of the atomic ratio of carbon at a point when the distance from the surface of the thin film layer in the film thickness direction of the thin film layer is further changed by 20 nm.
