An objective lens facing the optical disk is held by a lens holder, and this lens holder is supported by a leaf spring so as to be movable in the optical axis direction of the objective lens, and the base end of the leaf spring is supported. The rotating frame is rotatably supported by a support shaft arranged parallel to the optical axis of the objective lens, and the lens holder is driven to correct in the direction of deformation of the leaf spring and the direction of rotation of the rotating frame. In the correction drive device for an optical pickup, which is provided with a magnetic drive mechanism for causing the rotation, a part of the rotating frame is extended to an intermediate position of a leaf spring, and the support shaft is provided at an intermediate position of the leaf spring. A correction drive device for an optical pickup, characterized in that:
