<p>A foreign matter removal unit (400) includes a rectangular optical member (410) disposed on an optical path, in which is set an optically effective region through which a light flux passes, a piezoelectric device (430) provided to a side of the optical member (410) on the outer side of the optically effective region, and a vibration suppression member (470a, 470b, 570, 670, 770) provided to a side of the optical member (410) where the piezoelectric device (430) is not provided. The vibration suppression member (470a, 470b, 570, 670, 770) is provided to the optical member (410) such that an edge face of the side of the optical member (410) does not protrude out from an edge face of the vibration suppression member (470a, 470b, 570, 670, 770).</p> |
