A planar light emitting body 6 configured to emit a first illumination light, and a semiconductor light emitting element 7 configured to emit light toward the planar light emitting body 6 are disposed in a lamp chamber 5 defined by a lamp housing 2 having an opening and a cover 3 that covers the opening. The planar light emitting body 6 includes a transmitting layer through which light is caused to pass, and a control layer configured to irradiate light as a second illumination light by controlling a travelling direction of the light that is emitted from the semiconductor light emitting element 7 and passes through the transmitting layer.
