1. A vehicle headlamp, comprising:
- an excitation light source that emits excitation light;
a light emitting part that emits light upon receiving the excitation light emitted from the excitation light source; and
a reflection mirror that reflects the light emitted from the light emitting part,the light emitting part having a luminance greater than 25 cd/mm2, andthe reflection mirror having an aperture plane whose area size is less than 2000 mm2, the aperture plane being perpendicular to a direction in which the light travels outward from the vehicle headlamp.

Abstract
A headlamp 1 includes a laser diode 3 that emits a laser beam, a light emitting part 7 that emits light upon receiving the laser beam emitted from the laser diode 3, and a reflection mirror 8 that reflects the light emitted from the light emitting part 7. According to the headlamp 1, the light emitting part 7 has a luminance greater than 25 cd/mm2, and an area size of an aperture plane 8a perpendicular to a direction in which an incoherent light travels outward from the headlamp 1 is less than 2000 mm2.
