PROBLEM TO BE SOLVED: To provide a coated tool improved in welding resistance at high temperatures, restraining diffusion to a coating film of an element of a workpiece, and suitable for dry cutting work of a high speed and a high feed rate without sacrificing abrasion resistance and the adhesion of the coating film superior in oxidation resistance such as a (TiAl)N coating film. SOLUTION: The tool is coated with a coating film composed of one of nitride, carbonitride, oxynitride and oxycarbonitride including Ti and B in a base body surface as a metal element, and is composed of the coated tool characterized in that the coating film includes a nitride phase of B; the binding energy of B and N is confirmed by a ESCA analysis; and the presence of c-BN and/or h-BN is confirmed by a Raman spectroscopic analysis.
