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 content ratios of the cubic boron nitride and the binder phase are each in a specific range, the binder phase contains a Ti compound phase, an Al compound phase, and a W element-containing phase, content ratios of the Ti compound phase, the Al compound phase, and the W element-containing phase are each in a specific range, the W element-containing phase contains at least one selected from the group consisting of W2B and WB, and I2/I1, which is a ratio between an X-ray diffraction peak intensity of a (111) plane of the cubic boron nitride, I1, and a sum of X-ray diffraction peak intensities of a (211) plane of W2B and a (110) plane of WB in the binder phase, I2, is in a specific range.
