Abstract
A coated member of the present invention includes a substrate and a hard coating film that is formed on the surface of the substrate and includes a nitride or carbonitride of a metal element. A content of Al is 65 atom % or more and 85 atom % or less, a content of Cr is 15 atom % or more and 35 atom % or less, and a total content of Al and Cr is 90 atom % or more and 100 atom % or less in a total amount of the metal element and metalloid element contained in the hard coating film, and in an intensity profile obtained from a selected area diffraction pattern of a transmission electron microscope, a crystal plane exhibiting a maximum peak intensity is different between a vicinity of the substrate and a vicinity of the surface, in the vicinity of the substrate, a peak corresponding to a (111) plane or a (200) plane of a face-centered cubic lattice structure exhibits a maximum intensity, and in the vicinity of the surface, a peak intensity corresponding to a (220) plane is 0.6 times or more a larger one of a peak intensity corresponding to the (200) plane and a peak intensity corresponding to the (111) plane of the face-centered cubic lattice structure.
