A light emitting device that can reduce the illuminance unevenness on an illuminated surface. First light flux controlling member 103 controls the distribution of light emitted from light emitting element 102. Second light flux controlling member 105 has second incidence surface 201 onto which the light emitted from first light flux controlling member 103 is incident and second emission surface 202 that is located on a side opposite to second incidence surface 201 and emits the light incident from second incidence surface 201. Also, at least one surface of second incidence surface 201 and second emission surface 202 refracts the light having an optical path on a virtual cross-section including optical axis P1 of light emitting element 102 and being incident onto second incidence surface 201 or second emission surface 202 more to the optical axis P1 side than when being incident onto a plane perpendicular to optical axis P1.
