摘要： Provided is a cubic boron nitride sintered body including more than or equal to 85 volume percent and less than 100 volume percent of cubic boron nitride particles, and a remainder of a binder, wherein the binder contains WC, Co, and an Al compound, the binder contains W2Co21B6, and, when IA represents an X-ray diffraction intensity of a (111) plane of the cubic boron nitride particles, IB represents an X-ray diffraction intensity of a (100) plane of the WC, and IC represents an X-ray diffraction intensity of a (420) plane of the W2Co21B6, a ratio IC/IA of the IC to the IA is more than 0 and less than 0.10, and a ratio IC/IB of the IC to the IB is more than 0 and less than 0.40.
