Abstract: In the light flux controlling member (5), the angle between an optical path of light output from the light emission center (14) of a light emitting element (4) and optical axis L1 is θ2. Light is incident on the light flux controlling member (5) through an input surface and travels inside the light flux controlling member at an angle θ2 with respect to optical axis L1. Then, light is output from a light control output surface (10) at an angle θ3 with respect to optical axis L1. The input surface (15) and the light control output surface (10) are formed such that, in a range 0 θ2 when θ1 increases, and the relationship between θ1 and θ3 is reversed from θ1 θ3 when θ1 increases.
