An impact drive actuator comprises a vibrator fixed to a fixing member and configured to generate slight displacement in a first direction and a second direction, a vibration member configured to reciprocate by the slight displacement of the vibrator, a motion object set on the vibration member, an adsorption power control part configured to control adsorption power between the motion object and the vibration member, and a guide member having an end fixed to the fixing member, and provided along the vibration member. The motion object is supported clamped between the vibration member and the guide member so as to be engaged with each of the vibration member and the guide member. The adsorption power controlled by the adsorption power control part creates a difference between frictional force between the motion object and the vibration member and frictional force between the motion object and the guide member.
