A vehicle headlamp is configured to have a plurality of lamp units employing light-emitting diodes as light sources. One lamp unit takes as a light source a light-emitting diode into which a single light-emitting chip is packaged. Other lamp units may take as light sources light-emitting diodes into which a plurality of light-emitting diodes are packaged. A diffusion area is formed by means of radiation of light output from the lamp units.
