To provide a vehicular headlight which can acquire a favorable light distribution pattern.SOLUTION: A reflector 4 includes a rotary paraboloid system reflection surface 4a in which a focal point is positioned on a first light source side which is arranged further on the rear side than a second light source. The rotary paraboloid system reflection surface 4a is divided into a plurality of reflection regions 40, and by controlling the reflection direction of first light reflected in each reflection region 40, a light distribution pattern P1 for a low beam is formed. The plurality of reflection regions 40 reflects first light L1A, L1B incident into each reflection region 40 arranged on one side in the width direction sandwiching an optical axis of the first light toward the other side in the width direction sandwiching the optical axis of the first light, and reflects first light L1C, L1D incident into each reflection region 40 arranged on the other side in the width direction sandwiching the optical axis of the first light toward the one side in the width direction sandwiching the optical axis of the first light.SELECTED DRAWING: Figure 2

    【課題】良好な配光パターンが得られる車両用前照灯を提供する。【解決手段】リフレクタ4は、第2の光源よりも後方側に配置された第1の光源側に焦点が位置する回転放物系反射面4aを有し、回転放物系反射面4aは、複数の反射領域40に分割されると共に、各反射領域40で反射される第1の光の反射方向を制御することによって、ロービーム用配光パターンP1を形成しており、複数の反射領域40は、第1の光の光軸を挟んだ幅方向の一方側に配置された各反射領域40に入射した第1の光L1A,L1Bを、第1の光の光軸を挟んだ幅方向の他方側に向けて反射すると共に、第1の光の光軸を挟んだ幅方向の他方側に配置された各反射領域40に入射した第1の光L1C,L1Dを、第1の光の光軸を挟んだ幅方向の一方側に向けて反射する。【選択図】図2
