Abstract
Disclosed is a luminous flux control member () comprising: a lid section () positioned, via an air layer, over one or two or more light-emitting elements () positioned on top of a substrate (), and formed so as to intersect with the optical axis of the light-emitting elements (); and side wall sections () that extend from the outer edge of the lid section () towards the substrate () side. The inner surface () of the lid section () is a concave surface with the center section thereof positioned closer to the light-emitting elements () than the outer peripheral section, and is covered by a transparent reflective film (). The transparent reflective film () reflects some of the light from the light-emitting elements () towards the side wall sections () and allows the remaining light from the light-emitting elements () to pass through.
