PROBLEM TO BE SOLVED: To provide a cosmetic device having an electrode part conforming to a shape of a face.SOLUTION: In the cosmetic device equipped with a body casing having the electrode part on a surface for outputting an electric current for performing a cosmetic application and a gripping part which extends from the electrode part side and is formed in an integrated manner, the electrode part has a truncated pyramid shape having an upper surface and a rising part. The upper surface has at least a curved line part bulging to the side of the gripping part and a straight line part along the longitudinal direction of the gripping part. The curved line part and the rising part are connected by a first arc surface, and the straight line part and the rising part are connected by a second arc surface. The first arc surface has a curvature smaller than that of the second arc surface.COPYRIGHT: (C)2011,JPO&INPIT【課題】顔の形状に適した電極部を有す美容機器を提供する。【解決手段】美容を行うための電流を出力する電極部を表面に設け、前記電極部側から伸延する把持部を一体形成した本体ケーシングを備えた美容機器において、前記電極部は、上面と立ち上がり部を有す略錐台形状であり、上面は少なくとも把持部側に膨らんだ曲線部と把持部の長手方向に沿った直線部を有しており、曲線部と立ち上がり部は第1円弧面で結ばれ、直線部と立ち上がり部は第2円弧面で結ばれており、上記第1円弧面は第2円弧面より曲率が小さいこととした。【選択図】図1
