In a vehicle lamp device, light emitted by a LED enters a concentration element of a lens and is irradiated from an irradiating face of the concentration element. The reflecting face of the concentration element surrounds a central axis of the concentration element. Light that enters the concentration element is reflected by the reflecting face toward a central axis side of the concentration element, and light reflected by the reflecting face is irradiated from the irradiating face. The concentration element is thus able to efficiently concentrate light emitted by the LED.
