The present invention relates to a haptic actuator for generating vibration and, particularly, to a vibration actuator capable of maintaining vibration force and reducing a falling time of vibration after the applied power is cut off. The haptic actuator of the present invention vibrates using electromagnetic force, generated by a magnet and a coil, and includes: a case having an accommodating space formed therein; a fixing member fixed and mounted at the case; a vibration body for vibrating in the left and right directions of the fixing member in the accommodating space; an elastic member bent several times so as to elastically support the vibration body such that an initial location thereof is maintained; and an insertion member inserted and arranged in a corrugated space formed by the bending of the elastic member, wherein, when the vibration body vibrates in the left and right directions by the elastic force of the elastic member after the electromagnetic force is removed therefrom, the insertion member reduces the falling time of the vibration body in opposition the elastic force of the elastic member.
