An illumination apparatus which illuminates an illumination object region, comprises a lighting unit which distributes the current supplied by a current supply unit to a predetermined number of the light emitting elements among a plurality of light emitting elements so that the light emitting elements are lighted, a light guide unit which has a light take-in portion, relatively moves the light take-in portion with respect to the light emitting elements, and guides the light taken in by the light take-in portion to the illumination object region, and a timing control unit which controls the lighting unit in synchronization with movement of the light take-in portion of the light guide unit. The lighting unit sequentially lights the light emitting elements positioned in the vicinity of the light take-in portion of the light guide unit every predetermined number of the elements based on control by the timing control unit.
