Abstract
There is provided a surface-coated body equipped with a hard film that has high adherence and exerts excellent wear resistance. In a surface-coated body in which the surface of a base body is coated with at least one layer of a hard film constituted of one or more of nitride, nitrooxide, carbonitride and carbonitrooxide including at least Ti and Al, the hard film contains 0.01-1% by mass of one or more inert gas elements selected from He, Ne, Ar, Xe, Kr and Rn based on the total mass of the hard film, and, among peaks detected with the X-ray diffraction method for the hard film, the peak caused by the (111) plane of the crystal has the highest intensity.
