PROBLEM TO BE SOLVED: To provide a compact blur correction unit capable of performing position detection of high precision when correcting blur, a lens barrel, and a camera. SOLUTION: A blur correction unit (100) includes: photographic optical systems (L1 to L4); a movable optical member (L3) which is a part of photographic optical systems or another optical member and is provided so as to be movable relatively to the photographic optical systems; magnetic sensors (31X and 31Y) for use in position detection of the movable optical member; and a coil (19) which has a winding center line (Q) of winding disposed on a plane approximately parallel and approximately level with a plane on which the magnetic sensors are disposed.
