PROBLEM TO BE SOLVED: To provide an ultrasonic vibration device prevented from generating spurious components between resonance frequency and antiresonance frequency in impedance characteristic of a thickness direction and a beauty appliance using it. SOLUTION: The ultrasonic vibration device 40 comprises an ultrasonic transducer 1 for generating ultrasonic vibration and a horn 2 having a connecting surface 2b for connecting the ultrasonic transducer 1 and an ultrasonic transmitting surface 2a as a reversed flat surface for transmitting ultrasonic waves toward a target site. The horn 2 has an area wherein the diameter direction size along the thickness direction is kept in a constant size, and it is configured to be less than 50% of thickness direction.
