Abstract
A vehicular lighting device from which a fluorescent material is omitted that may cause deterioration of color rendering properties and occurrence of color separation is provided. The vehicular lighting device can have higher in color rendering properties than a conventional white light source obtained by combining a semiconductor light-emitting element such as an LD and the fluorescent material (wavelength converting member) and can suppress occurrence of color separation. A vehicular lighting device of the presently disclosed subject matter includes a supercontinuum light source that outputs supercontinuum light containing a visible wavelength region, and an optical system that controls the supercontinuum light output by the supercontinuum light source.
