An optical apparatus includes a photographic lens and a vibratory actuator
configured to move the photographic lens. The vibratory actuator includes
a vibration member having an electro-mechanical energy conversion
function for generating vibration and a contact member contacting the
vibration member. At least one press-contact surface of the vibration
member and the contact member is configured into an arc shape having a
central axis corresponding to a moving direction of the photographic
lens.
