    • An optical apparatus is disclosed in which a press contact force for bringing a vibrator and a contact member into press contact with each other is generated between them, and thereby the reaction force of the press contact force is difficult to transmit outward. The optical apparatus comprises a lens holding member which holds a lens, and a vibration type linear actuator which drives the lens holding member in an optical axis direction. The vibration type linear actuator includes a vibrator on which vibration is produced through an electromechanical energy conversion action and a contact member which is in press contact with the vibrator. The vibrator and the contact member is in press contact with each other by a magnetic force acting between them.
