PROBLEM TO BE SOLVED: To improve safety by performing radiation on a road surface just before a vehicle and preventing generation of any spots where a driver is not able to watch surely. SOLUTION: In a vehicular headlamp 1, an upper half part of a reflection mirror 2 is divided into at least three sections in a horizontal direction. The headlamp 1 radiates a distance of a road surface from the reflection surface belonging to a middle stage part 2b in the sections, and it radiates just forward the road surface from the reflection surface belonging to an upper stage part 2a of the sections, and it radiates an intermediate spot of the road surfaces radiated from the middle stair part 2b and the upper stair part 2a, in a lower stage part 2c of the sections. Accordingly, such a headlamp 1 that a luminous distribution characteristic is formed by means of a reflection mirror 2 radiates a road surface just before a vehicle where radiation can be not performed in the conventional case, and it is possible to prevent generation of any spots where a driver is not able to watch surely.
