This light flux control member includes an incidence surface, a plurality of total reflection surfaces, and a plurality of emitting surfaces. The incidence surface includes a first incidence surface intersecting Z-axis which is along an optical axis of a light emitting element, a second incidence surface intersecting X-axis, and a third incidence surface intersecting Y-axis. A first total reflection surface reflects, toward a first light guide part, light incident on the first incidence surface. A second total reflection surface reflects, toward a first emitting surface, light which is incident on the second incidence surface and advances without being reflected by the first total reflection surface. A third total reflection surface reflects, toward the first emitting surface, at least the light reflected by the first total reflection surface. The first emitting surface emits the light reflected by the second total reflection surface or the third total reflection surface. The third total reflection surface reflects, toward a second emitting surface, light incident on the third incidence surface. The second emitting surface emits the light reflected by the third total reflection surface. |
