Abstract
There is provided a lens barrel including an imaging optical system, and an image blur correction unit moving a shift lens forming the imaging optical system in a plane perpendicular to an optical axis of the imaging optical system. The image blur correction unit includes a second movable body holding the shift lens and provided to be movable in two directions perpendicular to each other on a plane perpendicular to the optical axis. A fixed lens holding frame holding a fixed lens forming the imaging optical system is placed in front of the second movable body. A movement control structure is provided in a region ranging from the second movable body to the fixed lens holding frame to allow movement of the second movable body in the two directions and control a range of movement of the second movable body.
