摘要：
The present disclosure relates to an electric toothbrush, and more particularly, to an electric toothbrush, which has excellent vibration efficiency since vibrations of the vibration motor are directly transferred to the bristle holder, saves the battery power, reduces a size of the toothbrush, decreases the thickness of the head portion, allows the vibration motor to be stably fixed in a fixing groove formed at the upper surface of the head portion, and reduces noise.
