An optical deflector comprises a vibration system and a driver. The vibration system includes a first oscillatory moving element having a reflecting surface, a second oscillatory moving element, and a support. The first and second oscillatory moving elements are resiliently supported respectively by first and second torsion springs to be able to torsionally vibrate about an oscillation axis with respect to the second oscillatory moving element and to the support. The vibration system has natural oscillation modes with different frequencies about the oscillation axis. The first and/or second torsion spring has torsion leaf portions torsionally deformed about torsion axes parallel to the oscillation axis. One end of each torsion leaf portion is coupled to an end of another through a connecting portion, and the other end is coupled to one of the first and the second oscillatory moving elements and the support directly or through a connecting portion.
