Abstract
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 TiBand contains substantially no AlN and/or AlO, the binder phase has a TiB(101) plane that shows a maximum peak position (2θ) in X-ray diffraction of 44.2° or more; and I/Iis 0.10 or more and 0.55 or less, where denotes an X-ray diffraction intensity of a (111) plane of the cubic boron nitride and Idenotes an X-ray diffraction intensity of a (101) plane of TiBof the binder phase.
