Ultrasonic generator and skin care device using the same

摘要

An ultrasonic generator includes an ultrasonic vibrator (1) generating ultrasonic vibration, a horn (16) and a retainer mechanism attaching and fixing the horn in place. The horn includes a flat plate-like horn having opposite flat surfaces (16,16b), one of which forms a connection surface connected to the ultrasonic vibrator and the other of which forms a ultrasonic wave emitting surface from which ultrasonic waves are emitted toward a target point. A support portion for use in attaching and fixing the flat plate-like horn by means of the retainer mechanism (45) is formed on an outer circumferential surface (17) of the flat plate-like horn with a thickness smaller than that of the flat plate-like horn of the flat plate-like shape.
