PROBLEM TO BE SOLVED: To provide an ultrasonic multifrequency vibrator having a plurality of resonance points near reference frequencies and capable of radiating ultrasonic wave with respective frequencies by being operated with the frequencies of these resonance points.;SOLUTION: The ultrasonic multifrequency vibrator 10 having a shape extended in an axial line AX direction comprises main parts 11A and 11B and a joints 12A installed between them. The main parts 11A and 11B are configured to resonate by ultrasonic wave vibration at reference frequency f0 if the main parts are taken out by themselves. Th joint 12A has a length LS in the axial line AX direction satisfying 0 LS s/2. The ultrasonic multifrequency vibrator 10 has a frequency characteristic that two or less resonance points for resonating the entire body appear near the reference frequency f0.;COPYRIGHT: (C)2008,JPO&INPIT
