PROBLEM TO BE SOLVED: To provide a beauty treatment instrument capable of eliminating an accident such as shunt caused by intrusion of a beauty treatment liquid by reliably preventing the beauty treatment liquid from entering inside a skin head.SOLUTION: The beauty treatment instrument includes, at a body case 1 and a skin head 2, a skin stimulation body 3 coming into contact with a skin surface to supply heat and a current thereto, and light sources 26 for applying light to the skin surface. A light guide body 27 is disposed between a window opening 35 opened to the skin stimulation body 3 and the light sources 26, for guiding the light applied from the light sources 26 to the outside of the window opening 35. A gap between the skin stimulation body 3 and the light guide body 27 for communicating the inside to the outside of the skin stimulation body 3 via the window opening 35 is liquid-tightly sealed by a first seal body 52 disposed between the skin stimulation body 3 and the light guide body 27.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】美容用液が肌ヘッドの内部に浸入するのを確実に防止でき、従って美容用液の浸入に伴う短絡などの事故を一掃できる美容器具を提供する。【解決手段】美容器具は、本体ケース1および肌ヘッド2に、肌面と接触して温熱および電流を供給する肌刺激体3と、肌面に光を照射する光源26が設けてある。肌刺激体3に開口した窓開口35と光源26の間に、光源26から照射された光を窓開口35の外へ導く導光体27を配置する。窓開口35を介して肌刺激体3の内部と外部を連通する肌刺激体3と導光体27の間の隙間が、肌刺激体3と導光体27の間に配置した第1シール体52で水密状に封止してあることを特徴とする。【選択図】図1
