A light flux controlling member includes: an incidence surface; a first total reflection surface, and two light guiding parts; two second total reflection surfaces disposed at respective end portions of the two light guiding parts and formed such that a distance between the second total reflection surface and a virtual plane increases as the second total reflection surface extends from the end portions, the virtual plane including the optical axis and a first virtual line which intersects the optical axis and extends in an extending direction of the two light guiding parts, the two second total reflection surfaces being surfaces on which light which is incident on the incidence surface and directly reaches the two second total reflection surfaces is incident at an angle equal to or greater than a critical angle, the two second total reflection surfaces being configured to reflect the light; and two emission surfaces.
