To provide a luminaire capable of surely dividing lights which are emitted from two types of light sources, and making a light emitted from one light sources an indirect light.SOLUTION: A luminaire comprises: a first light emission part comprising a first light emission body which emits a light by itself, and emitting the light emitted by the first light emission body for illuminating an indoor; a second light emission part which is provided on an external side of the first light emission part in viewing in a direction directed to a ceiling from the indoor, comprises a second light emission body which emits a light by itself, and emits the light emitted by the second light emission body; and a reflection board being arranged between the first light emission body and the second light emission body so as to protrude to the indoor side from the ceiling. The reflection board comprises: a light block surface for preventing the light emitted by the first light emission body from entering a light emission region to which the light is emitted by the second light emission body; and a reflection plane for turning an emission direction of the light emitted from the second light emission body to a direction which is different from an emission direction of the light emitted from the first light emission body and reflecting the light toward the ceiling.SELECTED DRAWING: Figure 5
