Vehicular headlamp

A vehicular headlamp (400) for emitting light toward a predetermined emitting direction, includes: a plurality of semiconductor light emitting devices (102a,102b,102c,102d,102e) approximately aligned; and an optical component (104), having its optical center (F) on one of the semiconductor light emitting devices (102a,102b,102c,102d,102e), for irradiating light emitted by the semiconductor light emitting devices toward the emitting direction.
