A cutting tool in which wear resistance is improved by suppressing sudden chipping on the flank face while suppressing oxidation of the coating layer on the rake face, and thereby has a long lifespan even under cutting conditions in which deposition and edge damage easily occur. In the cutting tool, a coating layer represented by Ti1-a-b-cAlaWbMc(C1-xNx), with M selected as at least one of silicon, yttrium, and a metal belonging to group 4, 5, or 6 on the periodic table, excluding titanium and tungsten, and 0.3≦a≦0.6, 0.01≦b≦0.2, 0≦c≦0.2, and 0≦x≦1, being provided on the surface of a main cutting tool body having a flank face and a rake face, and the content ratio of tungsten on the flank face is higher than the content ratio of tungsten on the rake face.
