PROBLEM TO BE SOLVED: To provide a lens unit and an imaging apparatus capable of attaining the miniaturization. SOLUTION: The lens unit includes: a lens barrel 11 wherein an imaging optical system is arranged; a movable part 49 including a movable lens, and moved related to the lens barrel in the optical axis direction; a linear actuator 68 for moving the movable part in the optical axis direction; a biasing leaf spring 39 including a holding part 41 for holding the movable part, a plurality of elastically deformable spring parts 42 for biasing the movable part to the optical axis direction and an attachment part 43 to be attached with the lens barrel, and also a biasing leaf spring 39 whose thickness direction is coincident with the optical axis direction. The holding part of the biasing leaf spring is formed to a circular-arc shape, and at least part of the spring part of the biasing leaf spring is formed so as to extend in a direction nearly along the holding part on the outer peripheral side of the holding part.
