PROBLEM TO BE SOLVED: To provide a projector headlight for a vehicle capable of mitigating the light-dark contrast at the boundary line of a light distribution pattern for passing beam and free of generation of a bad effect such as an irregular color, etc. SOLUTION: At the front surface 18a of a condenser lens 18 consists of a flat convex lens, an up-deflecting prism lens element 18s is formed extending in the horizontal direction along the intersection of the front surface 18a with a horizontal plane including the optical axis Ax of a lighting fixture. Thereby the light-dark contrast at the boundary line of a light distribution pattern for passing beam is mitigated by the up facing deflecting bundle of beams which passes the condenser lens 18 and is radiated forward from the lens element 18s. In the neighbouring region of the intersection L on the condenser lens front surface 18a, the reflected light from the reflection surface 14a of a reflector 14 is not incident to the peripheral edge of the condenser lens 18, so that there is no risk that an irregular color is generated in the light distribution pattern by the up facing deflecting bundle of beams radiated forward from the lens element 18s.
