Abstract
In a diamond-coated tool, a flank face of a tool base material includes a first flank face continuously extending to a cutting edge, a second flank face located farther away from the cutting edge than the first flank face and located outside the first flank face when viewed from an inside of the tool base material, and a flank face-side stepped portion connecting the first flank face and the second flank face. A diamond-coated layer is provided on the first flank face and the flank face-side stepped portion.
