<p>PROBLEM TO BE SOLVED: To provide an optical device that uses an oscillation type actuator enabling a contact member and an oscillation member to be contacted with each other at a predetermined position in a direction orthogonal to a drive.SOLUTION: An optical device uses an oscillation type actuator that generates drive force between a contact member and an oscillation member, in which the contact member includes the oscillation member including an electro-machine conversion element and a magnet, the contact member being in contact with the oscillation member, and an oscillation is excited to the electro-machine conversion element. In the optical device, the oscillation type actuator, in which when viewing from a driving direction, the magnet is arranged on both sides of the contact member in the oscillation member or a member having repelling magnetic force against the contact member and anchoring the oscillation member, is used to drive an optical member.</p> |
