To obtain main beams having no hole since there rises a hole in the beams at the position of the main beams when the shield is thick.

This is a headlight for automobile and is constructed of a reflector R, two light sources, an optical means A in front of the reflector, and a shield between the light source and the optical means. The reflector is composed of two portions divided at the longitudinal surface near the light sources and each has a different focus, and a first portion is located on a first longitudinal surface and allocated a first function and a second portion located on the other surface of the longitudinal surface is allocated a second function. The first portion R1 of the reflector forms images Fg;Fh of the first light source Li, b1;bm1 arranged on a first one side P, Pm of the longitudinal surface on the shield or in the vicinity of it, and the second portion R2 of the reflector forms images Fd;Fb of the second light source L2, b2, bm2 arranged on the other one side of the longitudinal surface. Then, the one optical means is constructed of a first and a second lens portions arranged on each half surface of the longitudinal surface.
