CUBIC BORON NITRIDE SINTERED BODY AND COATED CUBIC BORON NITRIDE SINTERED BODY
A cubic boron nitride sintered body including cubic boron nitride and a binder phase, wherein a content of the cubic boron nitride is 40 volume% or more and 70 volume% or less; a content of the binder phase is 30 volume% or more and 60 volume% or less; an average particle size of the cubic boron nitride is 0.1 µm or more and 3.0 µm or less; the binder phase contains TiN and/or TiCN, and TiB2 and contains substantially no AIN and/or Al2O3; the binder phase has a TiB2 (101) plane that shows a maximum peak position (2θ) in X-ray diffraction of 44.2° or more; and I2/I1 is 0.10 or more and 0.55 or less, where I1 denotes an X-ray diffraction intensity of a (111) plane of the cubic boron nitride and I2 denotes an X-ray diffraction intensity of a (101) plane of TiB2 of the binder phase.
