Abstract
To provide a cutting tool that includes a coating layer capable of exhibiting optimum cutting performance in each of a cutting edge, rake face, and flank face. A cutting tool () includes a substrate () that is coated with a coating layer () composed of SiM(CN), where M represents at least one element selected from Ti, Al, Cr, W, Mo, Ta, Hf, Nb, Zr, and Y, 0.01≦a≦0.4, and 0≦x≦1, and that has a cutting edge () at an intersecting ridge line of a rake face () and a flank face (). The Si content ratio in the coating layer () on the rake face () is higher than that on the cutting edge ().
