Abstract
In a lens driver apparatus using a linear actuator, spaces for installing a driving coil and a driving magnet are reduced to contribute to making the lens driver apparatus smaller. The present invention relates to the lens driver apparatus including a body that is to be driven and to which a lens is attached, a guide axis to guide and allow the body to be driven to move freely in a direction of the optical axis, a driving coil being flat-wound and fitted to the body to be driven, and a driving magnet being disposed opposite side of the driving coil and along a direction of movement of the body to be driven. In the lens driver apparatus according to the present invention, the driving coil and the driving magnet are shaped in curved forms so as to conform to an outer shape of the lens.
