1 (a) and 1 (b) show an example of an ultrasonic cutting device to which an ultrasonic cutting resonator according to the present invention is applied. This ultrasonic cutting device has an actuator for a support column 1. An ultrasonic cutting resonator 5 attached to a mother horn 4 provided at a lower end of an actuator (pressurizing unit) 3 which is supported by a support 2 so as to be vertically movable, such as cheese placed on a mounting table 6. The body to be cut 7 is pushed down from above, and the body to be cut 7
It can be cut into slices.

As shown in FIG. 2 (a), the ultrasonic wave cutting resonator (hereinafter referred to as "resonator") 5 is fixed to the bottom surface of the mother horn 4 at a predetermined interval so as to face each other. A support plate 10, a wire 11 hung in parallel between the tips of the two support plates 10, and a screw 12 as a fixing means for fixing the wire 11 to the tip of the support plate 10 in a tensioned state. It is composed of
