CERAMIC BALL MATERIAL, METHOD FOR MANUFACTURING CERAMIC BALL USING SAME, AND CERAMIC BALL
A ceramic ball material according to an embodiment includes a spherical portion; and a band-shaped portion formed over a circumference of a surface of the spherical portion. In the ceramic ball material, the ceramic ball material has a ratio Rab/Rap of 0.70 or more and 1.03 or less, where Rab denotes an arithmetic average roughness on an outer peripheral surface of the band-shaped portion; and Rap denotes an arithmetic average roughness on an outer peripheral surface of the spherical portion.
