ABSTRACT:
A ceramic rotor is constituted by a shaft portion and a disk portion. The shaft portion and the disk portion are joined to constitute a single body by sintering. The shaft portion and the disk portion are so formed that the amount of contraction of the shaft portion at the time of sintering is larger by 0.1% to 3% than that of the disk portion such that compresson stress is induced in the disk portion.
