Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for attaining the densification of components with regard to a method for producing a ceramic component using cold hydrostatic pressurization molding and hot hydrostatic pressurization treatment. SOLUTION: With regard to ceramic powder molding and the hot hydrostatic pressurization treatment of a ceramic sintered body, ultrasonic vibration is applied during cold hydrostatic pressurization (CIP) and hot hydrostatic pressurization (HIP). By using a CIP device or a HIP device suppressing the occurrence of a defect and the formation of pores by bridging, the fillability of powdered matter and the fineness of a sintered body are promoted.
