To provide an electric toothbrush capable of giving a brush rotational motions and vibration motions.SOLUTION: An electric brush provided with a grip part 101 and a brush connection part 105 fitted to the same and having a brush 107 on an end side includes: rotational motion system components composed of a power unit 102 for rotational motions and a transmission shaft 103 of the rotational motions; sound wave vibration system components composed of a rotational brush 107a inside rotated by the rotational motion system members, a vibration element 106 that performs sonic or ultrasonic vibrations by the connection part 104 provided with a power source 106a of (ultra)sonic wave vibrations or by a power source 104 of the sonic or ultrasonic vibration, and a sensor component 106a in contact with the vibration element 106; and a vibration brush 107 which vibrates and moves by the sound wave vibration system components and is arranged outside. The connection part 104 separates the vibration element 106 side and the grip part 101 side, and fixes them to the grip part 101, so that it suppresses transmission of vibrations from the vibration system, and can give the brush the rotational motions and/or vibration motions.SELECTED DRAWING: Figure 1 【課題】 回転運動と振動運動をブラシに与えることができる電動歯ブラシを提供する。【解決手段】 把持部１０１とこれに装着し先端側にブラシ１０７を有するブラシ接続部１０５とを備えた電動ブラシは、回転運動の動力部１０２と、回転運動の伝達シャフト１０３とからなる回転運動系部品と、これにより回転運動する内側の回転ブラシ１０７ａと、（超）音波振動の動力源１０６ａを備えた接続部１０４と音波または超音波振動の動力源１０４により音波または超音波振動する振動素子１０６と、振動素子１０６に接触するセンサ部品１０６ａとから構成された音波振動系部品と、音波振動系部品により振動運動する外側に配置された振動ブラシ１０７と、を備え、接続部１０４は振動素子１０６側と把持部１０１側とを分離して把持部１０１に固定することにより振動系からの振動の伝達を抑制し、回転運動と振動運動の片方または両方をブラシに与えることができる。【選択図】 図１
