A cutting tool comprising a rake face and a flank face, the cutting tool being composed of a substrate made of a cubic boron nitride sintered material and a coating provided on the substrate, the cubic boron nitride sintered material including cubic boron nitride, the coating including a MAIN layer, in the MAIN layer, M representing a metal element including titanium, chromium, or both, the MAIN layer including crystal grains of M x Al 1-x N in the cubic crystal system, in the M x Al 1-x N, the metal element M having an atomic ratio x of 0.3 or more and 0.7 or less, the cubic boron nitride being contained at a ratio of 20% by volume or more with respect to the cubic boron nitride sintered material, n F < n R being satisfied, where n F represents a number of voids per 100 μm in length of the MAIN layer on the flank face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the flank face, and n R represents a number of voids per 100 μm in length of the MAIN layer on the rake face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the rake face, n D being 3 or less, where n D represents a number of droplets per 100 μm in length of the MAIN layer on the flank face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the flank face; wherein: a void means a linear gap having a length of 0.5 μm or more; and a droplet means a grain of metal that is present in a layer configuring the coating and has a predetermined size measured by SEM as described in the description. the cutting tool being composed of a substrate made of a cubic boron nitride sintered material and a coating provided on the substrate, the cubic boron nitride sintered material including cubic boron nitride, the coating including a MAIN layer, in the MAIN layer, M representing a metal element including titanium, chromium, or both, the MAIN layer including crystal grains of M x Al 1-x N in the cubic crystal system, in the M x Al 1-x N, the metal element M having an atomic ratio x of 0.3 or more and 0.7 or less, the cubic boron nitride being contained at a ratio of 20% by volume or more with respect to the cubic boron nitride sintered material, n F < n R being satisfied, where n F represents a number of voids per 100 μm in length of the MAIN layer on the flank face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the flank face, and n R represents a number of voids per 100 μm in length of the MAIN layer on the rake face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the rake face, n D being 3 or less, where n D represents a number of droplets per 100 μm in length of the MAIN layer on the flank face in a cross section of the MAIN layer obtained when the MAIN layer is cut along a plane including a normal to the flank face; wherein: a void means a linear gap having a length of 0.5 μm or more; and a droplet means a grain of metal that is present in a layer configuring the coating and has a predetermined size measured by SEM as described in the description. a void means a linear gap having a length of 0.5 μm or more; and a droplet means a grain of metal that is present in a layer configuring the coating and has a predetermined size measured by SEM as described in the description.
