Abstract:
A luminous flux control member (200) of the present invention has: a light input surface (210); total reflection surfaces (220), which are formed at positions facing a light emitting element with the light input surface (210) therebetween; two light guide sections (230), which are formed such that respective cross-sectional areas thereof are reduced in the direction to be away from the light input surface (210) and the total reflection surface (220), said light guide sections being formed at facing positions with the light input surface (210) and the total reflection surface (220) therebetween; and two light output surfaces (240), which are formed on the outer surfaces of the two light guide sections (230), respectively.
