A light emitting device according to an embodiment of the present invention includes a plurality of light emitting elements disposed on a substrate, and a light flux controlling member that is for controlling a distribution of light emitted from the plurality of light emitting elements, and disposed on the plurality of light emitting elements. The light emitting element is disposed in such a way that L1 is longer than L2 when the light flux controlling member is viewed in plan view, where the L1 is a length from the center of gravity of the light flux controlling member to the optical axis of the light emitting element, and the L2 is a length from the center of gravity of the light flux controlling member to the central axis of the incidence unit corresponding to this light emitting element.
