Abstract
An illumination device includes a light source that emits light-source light, a light recovery member that is disposed close to the light source in the vicinity of a lateral side of the light source, and has a light receiving surface inclined at a predetermined angle with respect to an optical axis extending from the light source to the front to face the optical axis or the vicinity of the optical axis, and a rod integrator that uniformizes light-source light from the light source and light-source light reflected by the light recovery member.
