Abstract

The present application discloses a ceramic sintered body in which both toughness and wear resistance are satisfied. The ceramic sintered body of the present disclosure contains a first compound and a second compound. The first compound is silicon carbide, and the second compound is a diboride of a Group 4 element. A ratio of the second compound in the ceramic sintered body is 50% by mass or more and 70% by mass or less. When a 300 µm × 300 µm region of a polished surface of the ceramic sintered body is divided into 400 sections of 15 µm × 15 µm and an area ratio of the first compound is specified for each of the sections, a coefficient of variation CV of the area ratio of the first compound is more than 0.14 and less than 0.23.
