The ceramic product of this invention is characterized in that the ceramic bearing constructed by being allowed to contact the ceramic outer ring slidably with the ceramic inner ring is provided with a latching member to prevent the transfer of the ceramic inner ring in the axial direction at the inner or the outer ring of said ceramic product. The bearing constructed by the sliding contact of -the ceramic inner ring with the ceramic outer ring can prevent the occurrence of the transfer of the inner ring in the axial direction with respect to the outer ring by providing a latching member which prevent the -transfer of the inner ring in the axial direction at the inner or outer ring. Accordingly, there is no anxiety of separation of the outer ring from the inner ring.
