Abstract: Light flux controlling member 140 includes first light flux controlling member 141 and second light flux controlling member 142. First light flux controlling member 141 includes incidence surface 143 on which a part of light emitted from light-emitting element 130 is incident, total reflection surface 144 that reflects a part of light incident on incidence surface 143 toward second light flux controlling member 142, and emission surface 145 that emits a part of light incident on incidence surface 143 and light reflected by total reflection surface 144. Second light flux controlling member 142 includes reflection surface 149 that reflects a part of light emitted from first light flux controlling member 141. Reflection surface 149 is a rotational symmetric surface with the optical axis LA of light-emitting element 130 as a rotation axis.
