A vehicular headlamp unit using a light-emitting element as a light source includes a projection lens on an optical axis that extends in a vehicle longitudinal direction, and first and second light source units arranged rearward of the projection lens. The first light source unit includes a first light-emitting clement, a first reflector arranged to cover the first light-emitting clement from above and structured to reflect light from the first light-emitting element forward toward the optical axis, and a first mirror component having an upward-facing reflective surface. The second light source unit includes a second mirror component including a downward-facing reflective surface, a second light-emitting element arranged on the second mirror component facing forward and diagonally downward, a second reflector structured to reflect light from the second light-emitting element upward, and a third reflector arranged downward of the second light-emitting clement which reflects light from the second light-emitting clement forward.
