PROBLEM TO BE SOLVED: To provide a vehicular headlamp capable of facilitating awareness in a peripheral view under a dark environment while driving at night time.SOLUTION: A vehicular headlamp which forms a predetermined light distribution pattern on a virtual vertical screen confronting a vehicle front surface includes a first light source 12, a second light source 22 and a third light source 32. The predetermined light distribution pattern at least includes: a central region including an intersection point between a horizontal line and a vertical line on the virtual vertical screen; peripheral regions arranged on both sides of the central region on the virtual vertical screen; and an intermediate region arranged between the central region and the peripheral regions on the virtual vertical screen, and in which a relatively moving mark passes while a vehicle is travelling. A first optical system is configured so as to irradiate the central region with the light radiated from the first light source 12, a second optical system is configured so as to irradiate the peripheral regions arranged on both sides of the central region respectively with the light radiated from the second light source 22, and a third optical system is configured so as to irradiate the intermediate region with the light radiated from the third light source 32. |
