摘要:
An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and/or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part.
