PROBLEM TO BE SOLVED: To provide a beauty device in which adjustment of temperature on a vibration plate part which contacts a skin is facilitated, and an area capable of vibrating on the vibration plate part, can be increased.SOLUTION: A beauty device 1 comprises: a tip end member 2 comprising a vibration plate part 21 for applying ultrasonic vibration to a skin, and an outer peripheral edge part 22 continuous to an outer edge of the vibration plate part 21； a temperature adjustment body 3 for changing temperature of the vibration plate part 21； and a heat transfer member 4 which is interposed between the temperature adjustment body 3 and the outer peripheral edge part 22. An ultrasonic vibrator 23 is attached to the vibration plate part 21. The heat transfer member 4 forms a part of a thermal conductive path containing the temperature adjustment body 3 and the vibration plate part 21. The tip end member 2 is held to a housing 5 in a state of exposing the vibration plate part 21. In the housing 5, the ultrasonic vibrator 23, the temperature adjustment body 3, and the heat transfer member 4 are stored.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】肌に接触する振動板部の温度調節が容易であり、振動板部における振動可能な面積を広くすることができる美容器具を提供する。【解決手段】美容器１は、肌に超音波振動を付与する振動板部２１と、振動板部２１の外縁に連なる外周縁部２２とを備えた先端部材２と、振動板部２１の温度を変化させる温度調整体３と、温度調整体３と外周縁部２２との間に介在する伝熱部材４とを有している。振動板部２１には、超音波振動子２３が取り付けられている。伝熱部材４は、温度調整体３と振動板部２１とを含む熱伝導経路の一部を構成している。先端部材２は、振動板部２１を露出させた状態でハウジング５に保持されている。ハウジング５の内部には、超音波振動子２３、温度調整体３及び伝熱部材４が収容されている。【選択図】図６
