The present invention relates to a method of focusing a generated energy efficiently on a target site by generating a single sound wave using a planar element that generates ultrasonic waves and focusing the generated sound wave on a target site. A sonic therapy apparatus is provided. A treatment probe unit, a device main body including a high-voltage pulse generation circuit and an AC boosting circuit, a signal cable connecting the treatment probe unit and the device main body, and a power cable. It is configured. By applying one to several tens of high-voltage pulse signals to the planar element within a predetermined time from the high-voltage pulse generating circuit 10, sound waves generated by the planar element are generated by an acoustic lens built in the depth adjusting gel pad. It can be focused and focused on the tip of the contact portion of the treatment probe section 2 for treatment.
