An ultrasonic wave generating apparatus includes: a generator including an electric power supply, a controller that generates a control signal, a liquid crystal display indicator, and a transducer drive circuit; and transducer portions. The generator includes: the controller having an internal memory or a port to which an external memory is inserted, and formed of a microcomputer to control the generator and the transducer portions; thyristor portions that are arranged respectively in the front and rear ends of the transducer portions, in which two thyristors are connected in series in the respective thyristor portions; snubber circuit portions that are connected in parallel with the respective thyristor portions; at least one transducer that is connected with the controller and is included in the transducer portions; and choke coils that are connected with one end of the respective transducers in the transducer portions.
