Abstract
A lens drive device may include a movable body, a support body supporting the movable body through a spring member, and a magnetic drive mechanism provided with a coil. The movable body includes a coil winding part, end parts for restricting a range of the coil winding part, and a changing part for changing a drawing direction of the coil. The spring member is disposed near the other end part of the movable body and electrically connected with winding start and winding end of the coil. A coil winding method for the lens drive device may include a drawing step in which a coil is drawn between end parts, a changing step in which a drawing direction of the coil is changed by the changing part, and a winding step in which the coil is wound around the coil winding part.
