Abstract
An imaging apparatus includes an imaging device operable to convert light to an electrical signal, a vibrating unit including an optical member arranged on a light-receiving surface side of the imaging device, a vibration applying unit arranged to contact the vibrating unit and vibrates upon application of a voltage, the vibration applying unit vibrating integrally with the vibrating unit to vibrate the vibrating unit, and a member operable to sandwich the vibrating unit and the vibration applying unit. A zero-amplitude reference plane of resonance produced by the integral vibration of the vibrating unit and the vibration applying unit is located on the vibrating unit.
