Abstract
A lens driving mechanism eccentrically drives at least one lens or lens subunit, hereunder called a correcting lens, in a lens system constituting a taking lens unit in a plane perpendicular to an optical axis direction, and includes a movable frame holding the correcting lens, two coils fixed at a lens barrel where the taking lens unit is disposed, and magnetic circuit formation members generating a magnetic field crossing the coils that are disposed around the correcting lens when viewed in the optical axis direction of the taking lens unit. The members include at least two magnets and yokes disposed at each of the two coils for generating movement forces in different directions perpendicular to the optical axis. The yokes oppose the respective magnets. Either the magnets or the yokes are held by the movable frame, and the other of the magnets and yokes are secured to the lens barrel.
