An unnecessary vibration detection apparatus of a vibration type actuator includes an AC voltage generation unit that generates a plurality of AC voltages having a driving frequency; a vibration detection unit that outputs a vibration detection signal of the vibration type actuator; and an unnecessary vibration detection unit that detects an unnecessary vibration component by generating a signal for cancelling the vibration component of the driving frequency in the vibration detection signal by controlling amplitudes of a plurality of AC signals which are used for generating the plurality of AC voltages.
