To provide an illumination apparatus by which an illumination region having a constant flat illuminance distribution is obtained at high illuminance while electric power is saved and which can extend the irradiation distance, and an illumination apparatus including the illumination unit. An illumination unit 100 using a light emitting diode 17 as a light source is provided with a light emitting unit 21 having a plurality of light emitting diodes 17 on a base 19; first reflecting sections 25 that are provided to correspond to the respective plurality of light emitting diodes on the light emitting side of the light emitting unit and reflect light from the light emitting diodes 17 toward the light emitting side to be substantially collimated; and a pair of second reflecting sections that are arranged on the light emitting side of the first reflecting section and reflect light from the light emitting diodes 17, which is not incident on the first reflecting sections 25, toward the light emitting side to be substantially collimated. |
