Abstract
A composite sintered material contains cubic boron nitride particles and binder particles. The composite sintered material contains 40 vol % or more and 80 vol % or less of the cubic boron nitride particles. The binder particles contain TiCN particles. The composite sintered material shows a first peak belonging to a (200) plane of the TiCN particles in a range in which a Bragg angle 2θ is 41.7° or more and 42.6° or less in an X-ray diffraction spectrum measured using a Cu-Kα ray as a ray source.
