Abstract: An electromagnetic flux controlling member includes an incidence surface for allowing incidence of an electromagnetic wave, and an emission surface for emitting the electromagnetic wave incident on the incidence surface to an outside. At least one of the incidence surface and the emission surface includes a base curved surface and a plurality of protrusions arranged on the base curved surface. Each of the plurality of protrusions includes a conical tip portion disposed such that at least a part of an edge of a bottom surface of the conical tip portion makes contact with the base curved surface, and a partially columnar leg portion disposed between the conical tip portion and the base curved surface. A central axis of the conical tip portion and a central axis of the partially columnar leg portion are parallel to a main axis of the electromagnetic flux controlling member.
