Abstract
A light flux controlling member of the present invention includes an incidence area and an emission area. The incidence area includes a plurality of protrusions each having an incidence surface, a reflection surface, and a ridge line. The reflection surface disposed outermost includes a plurality of split reflection surfaces that reflects light having entered the light flux controlling member toward the emission area, and one or two or more stepped surfaces disposed between the two adjacent split reflection surfaces and at a dead angle position relative to a traveling direction of the light having entered the light flux controlling member. The protrusion disposed outermost has a projection part projecting in a direction along a central axis, with a tip portion thereof being closer to the emission area than an end portion of the light flux controlling member on a light emitting element side is in the direction along the central axis.
