Abstract
A vehicular headlamp with a shade that even though the reflective surface of a reflector is constituted of a plurality of reflective elements, the generation of stray light is minimized while a decrease in utilization luminous flux is reduced to the minimum. The reflective surface (,) of a reflector (,) is constituted of a plurality of reflective elements,) that are the divided rectangular segments each of which is longer than is wide. The upper end edge B of the reflective surface (,) has a curved configuration having irregularities respectively in reflective elements (,). However, the rear end edge (,Aa) in the upper end portion (,A) of a shielding cap (,) is set to have a curved configuration obtainable from a line of intersection D between a horizontal plane forming an area (,A,) near the rear end edge of the upper end portion (,A) and an imaginary curved plane (C) formed by connecting together the light emission center (A) of a light source bulb (,) and the upper end edge (B) of each reflective element (,). Consequently, the incidence of light on the upper wall surface (,) can be stopped substantially without impeding the incidence thereof on the reflective surface (,).
