Abstract
A light flux controlling member has an incidence region and an emission region. The incidence region is assumed to have a plurality of virtual quadrangles that are disposed in such a manner that one fits into another, and have the same number of apexes as one another, and includes a plurality of convex parts each of which has a ridge line along a first virtual straight line that connects two adjacent apexes of the virtual quadrangle, and a plurality of wall portions each of which is disposed along a second virtual straight line that connects respective corresponding apexes of the virtual quadrangles. The wall portion is disposed continuously between a connection portion of the convex parts at an innermost side and a connection portion of the convex parts at an outermost side in the second virtual straight line.
