A lens barrel capable of being reduced in length in a collapsed position. Barrier members have an opening/closing operation plane that openably/closably covers the front face of an image-taking lens. A barrier drive mechanism causes the barrier members to perform opening/closing operation. A lens holding member has a holding portion that holds the image-taking lens and a guide portion that guides the image-taking lens in the optical axis direction. A lens drive mechanism causes the lens holding member to move forward or backward in the optical axis direction. A stroke area of the guide portion of the lens holding member is set to overlap the opening/closing operation plane of the barrier members in the optical axis direction.
