Abstract: A fat remover is disclosed, which comprises an upper main body including a plurality of connection terminals, a lower main body including an upper plate having a plurality of female rivets transmitting ultrasonic signals and low-frequency signals by contact with the connection terminals, a cup body having an opened bottom surface, a rubber plate interposed between the upper plate and the cup body, and a second lower plate inserted in the bottom surface of the cup body, and a skin contact sensor protruded on an inner lower part of the lower main body together with the ultrasonic vibration plate and the low-frequency vibration plate. Accordingly, the fat remover separately has the ultrasonic vibration plate and the low-frequency vibration plate, and performs fat removal after confirming a close contact between the skin and the vibration plates by the skin contact sensor, by applying stimulus to the skin contacting the vibration plates.
