A vehicular headlamp apparatus includes: a lamp body; a translucent cover (214) having a slanted portion (214a); and a lamp unit (10). A semiconductor light-emitting element (12) is mounted on a mounting surface (14a) so that an irradiation axis (X) intersects with an optical axis (O1) One end of the reflective surface (16a) of a reflector (16) is located on a vehicle rear side of the semiconductor light-emitting element (12). The other end protrudes toward a vehicle front from a vehicle front side end (14b) of the light source mounting portion (14). A protruding portion (16a3) of the reflective surface (16a), protruding toward the vehicle front from the vehicle front side end (14b), is provided to face the slanted portion (214a). The reflective surface (16a) is configured so that, within a low beam light distribution pattern, first, second and third areas respectively form a horizontal cut-off line, an oblique cut-off line and a diffusion portion. |
