An optical apparatus comprises a lens which can be moved in the direction of the optical axis, a moving unit for moving the lens, and a signal generator for detecting information about the movement of the lens, the signal generator comprising a wiring board which is disposed on a surface intersecting the optical axis at right angles and on which a signal generating pattern is formed, and a signal generating member which is moved around the optical axis by rotating the rotating member in the moving unit and which slides on the signal generating pattern. There is thus no need for providing a flexible printed wiring board, as conventional lens barrels.
