Abstract

Lamp piece units in a parabolic pillar type capable of forming a luminous intensity distribution pattern prolonged sideways are formed as side irradiating lamp piece units. Thereby, a portion of diffused and reflected light from reflectors of the respective side irradiating lamp piece units is prevented from being blocked by other lamp piece constituting members, even when a surface shape of a vehicular headlamp is flexed to the rear side. Further, although the respective side irradiating lamp piece units are constituted by the lamp piece units of the parabolic pillar type having an angular outer shape as a whole, a large depth space for arranging the units is dispensed with.
