Beschreibung
Zusammenfassung:	An optical element includes a substrate having an optically effective surface and an optically non-effective surface, and a light shielding film disposed over the optically non-effective surface. The optically non-effective surface has an inclined chamfer and a level chamfer that define a ridge portion. The ridge portion is coated with an aliphatic hydrocarbon.
