CUTTING TOOL

A cutting tool including a base material and a hard layer provided on the base material,in which the hard layer is composed of a compound represented by TiaAlbBcN,an atomic ratio a of a titanium element in the TiaAlbBcN is 0.25 or more and less than 0.55,an atomic ratio b of an aluminum element in the TiaAlbBcN is 0.45 or more and less than 0.75,an atomic ratio c of a boron element in the TiaAlbBcN is more than 0 and 0.1 or less,a sum of the atomic ratio a, the atomic ratio b and the atomic ratio c is 1,a ratio I(200)/I(002) of an intensity I(200) of an X-ray diffraction peak of a (200) plane to an intensity I(002) of an X-ray diffraction peak of a (002) plane in the hard layer is 2 or more and 10 or less, anda full width at half maximum of the X-ray diffraction peak of the (002) plane is 2 degrees or more and 8 degrees or less.
