<p>The technical task of the present invention is to provide an ultrasonic transducer for a high-intensity focused ultrasonic wave generator capable of minimizing impact of ultrasonic waves on areas other than a target by making the ultrasonic waves be focused on one point. To perform said task, the ultrasonic transducer for the high-intensity focused ultrasonic wave generator includes: a piezoelectric element which has a concave shape; a first electrode which is applied on the inner surface of the piezoelectric element; a second electrode which is applied on the outer surface of the piezoelectric element; and an intensity reducing unit which reduces the intensity of the ultrasonic waves generated at the center of the piezoelectric element.</p> |
