Abstract
An electric toothbrush includes a driving source; a vibrating member having a brush; a transmission mechanism which converts an output of the driving source into vibration of the vibrating member; and a control unit that controls the output of the driving source. The vibrating member has a first resonance point in which the brush resonates in a first direction, and a second resonance point in which the brush resonates in a second direction; and the control unit has a first operation mode which controls the output of the driving source so that a resonance in the first direction is generated, and a second operation mode which controls the output of the driving source so that a resonance in the second direction is generated.
