Of the total amount of metal elements and metalloid elements in the hard coating, the Al content is 65–85 atm%, the Cr content is 15–35 atm%, and the total Al and Cr content is 90–100 atm%. The crystal plane that represents the maximum peak intensity of an intensity profile obtained from a selected area diffraction pattern obtained by transmission electron microscope is different for the vicinity of the substrate and the vicinity of the surface. For the vicinity of the substrate, the peak that corresponds to the (111) or (200) plane of a face-centered cubic lattice structure represents the maximum intensity. For the vicinity of the surface, the peak intensity that corresponds to the (220) plane of a face-centered cubic lattice structure is at least 0.6 times the greater of the peak intensity that corresponds to the (200) plane of a face-centered cubic lattice structure and the peak intensity that corresponds to the (111) plane.
