ABSTRACT:
Arranged are an optical element, a piezoelectric element arranged on the optical element, and an oscillation circuit for causing the piezoelectric element to vibrate so as to generate vibrational waves, wherein the volume of the piezoelectric element is determined based on density of the piezoelectric element, mass of the optical element, and vibration speed of the optical element, and made a size such that there is no wasteful consumption of energy.
