PURPOSE: To flatten vehicular lighting device by indirect illumination by use of a plurality of LED light sources while allowing provision of sufficient light to the front side of the lighting device even when providing the lighting device in a vehicle body curved part. CONSTITUTION: In this lighting device, respective Fresnel lenses 32 making light from the respective LED light sources 30 parallel light are disposed such that the directions of the parallel light are aligned upward, and the parallel light from the respective Fresnel lenses 32 is reflected toward the front of the lighting device by a reflector 18. The reflector 18 is divided into small reflectors 24A-24E in respective areas on which the parallel light from the respective Fresnel lenses 32 is incident, and the small reflectors 24A-24E are disposed in stair shape such that the small reflectors 24A-24E are gradually displaced to the rear side of the lighting device from one end part in the right and left direction of the reflector 18 toward the other end part. Thereby, the reflected light from the respective small reflectors 24A-24E is radiated toward the front of the lighting device, while the reflector 18 can be formed such that the reflector 18 is curved to the rear side of the lighting device.
