Abstract
A light bundle control member of the present invention comprises: an entry plane on which light emitted from a light emitting element becomes incident; two reflecting planes which are arranged across the entry plane in positions opposing the light emitting element, and which respectively reflect some of the light entering via the entry plane in two directions that are substantially perpendicular to the optical axis of the light emitting element and opposed to each other; and two output planes which are arranged opposing each other across the two reflecting planes, and which respectively cause the light reflected by the two reflecting planes to be externally output. Each of the two output planes has a plurality of first ridges arranged thereon, wherein, as viewed from the output plane side, a ridge line of the plurality of first ridges is substantially parallel with the optical axis of the light emitting element.
