PROBLEM TO BE SOLVED: To sufficiently secure the luminosity of a high-intensity area in a light distribution pattern which is formed by radiation light from a projector-type vehicular lighting tool.SOLUTION: The luminance of a light emitting element 22A of a first light source unit 20A out of a plurality of the light source units 20A, 20BL and 20BR which are arranged at a rear side of a rear-side focus point F of a projection lens 12 is set at a value higher than the luminance of light emitting elements 22B of the respective second light source units 20BL, 20BR. By this constitution, a high-intensity area is formed with sufficient luminance by radiation light from the first light source unit 20A in a low-beam light distribution pattern which is formed by radiation light from a vehicular lighting tool 10, and a diffusion area is formed by radiation light from the second light source units 20BL, 20BR. |
