PROBLEM TO BE SOLVED: To suppress generation of stray light to the minimum while suppressing a degrease in optical flux used to the minimum even if a reflection surface of a reflector is constituted of a plurality of reflection elements in a vehicular headlight provided with a shade. SOLUTION: A reflection surface 20a of a reflector 20 is constituted of a plurality of reflecting elements 20s divided in a segmental form of a vertically elongated rectangle over the whole region thereof. The upper end edge B of the reflection surface 20a is formed into a curve having unevenness in each of the reflection elements 20. The shape of a rear end edge 24Aa at the upper end 24A of a light shielding cap 24 is set in a curve obtained as a cross line D between a horizontal surface constituting a region 24A1 in the vicinity of the rear end edge 24Aa at the upper end 24A, and an imaginary curved surface formed by connecting the light emitting center A of a light source bulb 18 to the upper end edge B of each of the reflection elements 20s. Consequently, light incidence to an upper wall surface 20c can be substantially inhibited while light incidence to the reflection surface 20a can be hardly inhibited.
