The present invention relates to a therapeutic ultrasonic wave generating device. The present invention includes: a rotating motor an ultrasonic wave generating unit being provided with a transducer generating ultrasonic waves and a focus rotation movement unit moving the focus of the ultrasonic waves generated by the ultrasonic wave generating unit in a circle on the same plane by receiving a transmission of rotational force of the rotating motor. The present invention enables: the focus of ultrasonic waves to be moved in the circle having a constant radius at a uniform depth under the skin and energy to be applied uniformly and evenly within the movement radius, thereby enabling enhancement of therapeutic performance.
