To provide a high beauty treatment effect by supplying ultrasonic vibrations to the skin, pressurizing the skin and making a stimulating current flow to the skin, etc.

Two of ultrasonic vibration generators 3A and 3B provided with a horn 11 composed of a metal material for which the surface shape of a tip part is formed into a smooth curved surface and a vibration transducer supplying the ultrasonic vibration to the horn 11 are used. The horns 11 of the two ultrasonic vibration generators 3A and 3B are pressed to the mutually different parts of the skin and the ultrasonic vibration is supplied simultaneously. Also, a voltage is applied between the horns 11 by a stimulating voltage generation circuit 5 and the stimulating current is made to flow to the skin.
