Provided are a sintered ceramic and a ceramic sphere which are inhibited from suffering surface peeling due to fatigue resulting from repetitions of loading and can attain an improvement in dimensional accuracy when subjected to surface processing and which have excellent wear resistance and durability. A ceramic-sphere inspection device is also provided with which a ceramic sphere is inspected for a flaw present in the surface layer and for snow flakes without destroying the ceramic sphere. The device is a ceramic-sphere inspection device (100) in which a ceramic sphere (S) is rotatably supported in a given position and illuminating light emitted from a light projector (110) is detected with a light receiver (120) to evaluate the state of the inner part of the surface layer, and has been configured so that the light receiver (120) does not detect the light emitted from the light projector (110) and reflected at the surface of the ceramic sphere.
