Provided is a method for coating a thin film on the outer surface of a casing, which imparts anti-corrosive property, environmental resistance and non-conductive property to the casing through a cost-efficient sputtering process. The method for coating a non-conductive alloy thin film capable of substituting for a dielectric film comprises the steps of: forming(S110) a sheet or a desired injection molded article; and coating(S120) an indium(In)-tin(Sn) thin film on the surface of the sheet or article through a sputtering process. The In-Sn alloy thin film is coated to a thickness of 1000 angstroms or less. The In-Sn alloy thin film comprises In and Sn in a mixing ratio of 100:1-50 wt%. |
