Abstract:
1. An optical apparatus comprising: a single driving magnet including a first face as an object-side face in which a first magnetic pole and a second magnetic pole are formed in a first direction different from an optical axis direction and a second face as an image-side face which is located on a reverse side to the first face in the optical axis direction and in which the first magnetic pole and the second magnetic pole are formed in a second direction different from the optical axis direction and the first direction; a first driving coil facing the first face of the driving magnet; a second driving coil facing the second face of the driving magnet; a first member holding the driving magnet; a second member holding the first and second driving coils; and a driven member held by one of the first and second members, the driven member being an optical element or a photoelectrical conversion element, wherein the one of the first and second members which holds the driven member is moved in the first direction by a driving force generated by the energization of the first driving coil, and the one of the first and second members which holds the driven member is moved in the second direction by a driving force generated by the energization of the second driving coil, and wherein, when viewed in the optical axis direction, the first coil, the first and second faces of the driving magnet and the second coil are arranged in one same phase region around the optical axis.
