To provide a technique that can prevent abnormal vibrations from occurring on a resonator and apply, to a cutting edge, vibrations with the magnitude of amplitude thereof adjusted in the direction of width of the edge, thereby cutting an object of interest with high accuracy.
The resonator 21 with a gripped portion grasped with clamp means 28 is supported by a support means 24, thereby preventing abnormal vibrations from occurring on the resonator 21. The resonator 21 has at least one elongated hole 26b defined on a side surface thereof, thus allowing for adjusting the amplitude magnitude of vibrations in the direction of width of the cutting edge 23 on one end of the resonator 21. This enables vibrations with the amplitude of an adjusted magnitude in the direction of width to be applied to the cutting edge 23. Accordingly, the cutting edge 23 which is adequately vibrated can be used to cut the object of interest with high accuracy.
