The lens barrel includes a first motor () that drives a third front lens group-holding frame (B) by first magnets (A) provided on the third front lens group-holding frame (B) and a first coil (C), and a second motor () that drives a fourth lens group-movable holding frame (B) by second coils (A) provided on the fourth lens group-movable holding frame (B) and second magnets (B) provided on a fourth lens group base-holding frame (A) fixed to the stationary barrel () and the cam barrel (). The third front lens group-holding frame (B) is fixed by a magnetic force between the first magnets (A) and inner and outer yokes (C,D) provided on the fourth lens group base-holding frame (A) in a case where the application of current to the first coil (C) is stopped.
