Abstract
An illumination apparatus is disclosed in which its efficiency as an optical system can be improved by effectively utilizing the luminous flux that was not used in conventional illumination apparatuses, and the positional relationship between a light source and an optical member can be set with accuracy. The illumination apparatus comprises a light source, and an optical member having a refractive surface on a side closer to an irradiation range than the light source. The optical member includes a holding portion which holds the light source.
