ABSTRACT:
The lens barrel includes a first lens unit, a second lens unit, and a drive unit. The first lens unit includes a first lens element and a first lens support frame supporting the first lens element. The second lens unit includes a second lens element and a second lens support frame supporting the second lens element. The second lens unit is supported by the first lens unit to be movable in the optical axis direction of the first lens element with respect to the first lens unit. The drive unit is arranged to be used to drive the second lens unit with respect to the first lens unit, and is fixed to the first lens unit. When viewed in the optical axis direction, the drive unit is fixed to the first lens unit so that a first profile line formed by the first lens unit and the drive unit is substantially circular.
