Patent ID: 7906217

Claim:
A vapor deposited film formed on a surface of a base material by a plasma CVD method by using an organic metal compound and an oxidizing gas as reaction gases; wherein said vapor deposited film is sectionalized into an adhesive layer on the side of the base material, an intermediate barrier layer and a surface protection layer, wherein each of said adhesive layer and said surface protection layer have a carbon concentration of not less than 5 element % on the total basis of a metal element (M), oxygen (O) and carbon (C) derived from said organic metal compound, and each of said adhesive layer, said intermediate barrier layer and said surface protection layer comprise a metal element (M), oxygen (O) and carbon (C), wherein the carbon concentration of said intermediate barrier layer is less than 5 element % on the total basis of a metal element (M), oxygen (O) and carbon (C) derived from said organic metal compound; said surface protection layer has the carbon (C) concentration higher than the oxygen (O) concentration and the metal element (M) concentration, and, at the outer surface of said surface protection layer, an element ratio (O/M) representing the degree of oxidation of the metal element (M) is not larger than 1.3, and the bonding energy of the metal element (M) of said surface protection layer is smaller than an average value of the bonding energy of the metal element (M) of said intermediate barrier layer by not less than 1.0 eV; and in said intermediate barrier layer, the element ratio (O/M) representing the degree of oxidation of the metal element (M) on average is larger than 1.8 but is not larger than 2.4.
