To provide a vehicular exterior component made visually recognizable in a metallic style with external light being intensive, meanwhile, illuminatable with the external light being weak, with a rate of wavelength component of an irradiation light at illumination made adjustable.SOLUTION: A vehicular exterior component 100 includes: a clear transparent member 101 which includes an external surface 101a directed outward of a vehicle and an internal surface 101b directed inward of the vehicle; a luminosity thin film 102 made of a metal which is provided on the internal surface 101b of the transparent member 101 and simultaneously reflects at least one part of the light entering from the external surface 101a to the transparent member 101 and at the same time penetrates through a remainder; and an interference film 103 which is disposed on the internal surface 101b side of the transparent member 101, interposing the luminosity thin film 102 made of the metal between the transparent member 101 and itself and simultaneously reflects or absorbs a part pf wavelength component which is included in an irradiation light L2 irradiated from the internal surface 101b side of the transparent member 101.SELECTED DRAWING: Figure 1 【課題】車両用外装部品を外光が強い場合に金属調に視認可能とし、外光が弱い場合に電飾可能とし、電飾時における照射光の波長成分の割合を調整可能とする。【解決手段】車両用外装部品１００は、車両の外部に向けられる外表面１０１ａと車両の内部に向けられる内表面１０１ｂを有する透明な透明部材１０１と、透明部材１０１の内表面１０１ｂに設けられると共に外表面１０１ａから透明部材１０１に入射した光の少なくとも一部を反射すると共に残部を透過する金属製光輝薄膜１０２と、透明部材１０１との間に金属製光輝薄膜１０２を挟んで透明部材１０１の内表面１０１ｂ側に配置されると共に透明部材１０１の内表面１０１ｂ側から照射される照射光Ｌ２に含まれる一部の波長成分を反射あるいは吸収する干渉膜１０３とを有している。【選択図】図１
