Abstract
A luminous flux control member () has: a light input region (), to which light having been outputted from a light emitting element () is inputted; and a light output region (), from which the light having been inputted from the light input region () is outputted. The input region () has: a refracting section (); a reflection fresnel lens section (), which is positioned outside of the refracting section (); and a reflecting surface (), which is positioned outside of the reflection fresnel lens section (). The reflecting surface () reflects, toward the light output region (), the light which has been inputted to the reflection fresnel lens section (), and which has not been reflected (the light leaked from the reflection fresnel lens section ()).
