PROBLEM TO BE SOLVED: To provide an infrared light reflector reduced in restriction regarding an installation position even if it is installed at a vehicle. SOLUTION: The infrared light reflectors 10, 11 and 12 are constituted in such a manner that a visible light cutting filter 200 for shutting off a visible light component and transmitting infrared light is adhered and fixed to the surface of a general light reflector 100 for reflecting visible light and the infrared light. The light reflector 100 mainly comprises a support plate 101, a light reflection plate 102 fixed to the main surface of the support plate 101 and a micro-prism 103 fixed to the main surface of the light reflection plate 102. The visible light cutting filter 200 is constituted by generally coating a gray type or a black type visible light cutting filter material, so-called a smoke material or adhering a tape-like visible light cutting filter.
