Abstract
The present disclosure provides an optical device that reduces stress concentration on a vibrator while removing foreign matter adhering to a light-transparent body covering the exterior of the optical device with vibrations, and to provide an image pickup unit including the optical device. An optical device includes an outermost-layer lens, a housing, a vibrator, and a piezoelectric device. The outermost-layer lens is transparent to light of a predetermined wavelength. The housing holds the outermost-layer lens. The vibrator is in contact with the outermost-layer lens held by the housing. The piezoelectric device is disposed on the vibrator to vibrate the vibrator. The vibrator is a tubular body, and includes a connector that is in contact with the outermost-layer lens, a vibrating portion on which a piezoelectric device is disposed, and a supporter that connects the connector and the vibrating portion to each other and that has a curved cross-sectional shape.
