Abstract
A light flux controlling member includes a concavity on which light is incident on, a light control/emission surface that controls a traveling direction of light incident on the concavity, and a back surface that extends in a radial direction from an opening rim part of the concavity. One of a grid convex part which arranges a plurality of strips of convex parts in a grid pattern and a grid concave part which arranges a plurality of strips of concave parts in a grid pattern is formed in the back surface. A method of manufacturing the light flux controlling member includes forming one of the grid convex part and the grid concave part integrally with a main body of the light flux controlling member by integral molding using a mold having a shape corresponding to one of the grid convex part and the grid concave part.
