Beschreibung
Zusammenfassung:	An optical component holding apparatus which is capable of easily correcting tilts of optical components by reducing distortion of the optical components themselves even if the optical components are not substantially circular. A first lens and a second lens which are the optical components are housed in a lens holder. An elastic member urges the first lens against a lens holder to determine a position of the first lens in a direction of an optical axis. The lens holder, the first lens, and the elastic member abut against one another at three positions that are substantially the same when the lens holder, the first lens, and the elastic member are viewed in the direction of the optical axis.
