Abstract
A light emitting device comprises a light emitting element and a light flux controlling member configured to control the distribution of light emitted from the light emitting element. The light flux controlling member comprises an incidence surface including an outer incidence surface including an inclining surface formed such that the distance from the light emitting element increases as the distance from the optical axis of the light emitted from the light emitting element increases and an inner incidence surface, a reflection surface disposed on a side of the light flux controlling member opposite to the incidence surface, and a emission surface disposed to surround the optical axis. Light emitted from the light emitting surface center of the light emitting element does not reach the inclining surface.
