Zusammenfassung:	To provide a lighting fixture unit in which while the cooling performance of a heat sink of the lighting fixture unit is improved, the size of the heat sink is reduced, and a vehicular lighting fixture.SOLUTION: A heat sink 2 of a lighting fixture unit comprises a base part 23 in which a light source unit is placed on a back surface of the base part 23 of the heat sink 2, and a plurality of fins formed on a front surface of the base part 23. The fins include a plurality of first fins 21 formed in nearly parallel with each other, and a second fin 22 formed in non-parallel with the first fins 21, and for guiding wind of a fan 4 to the first fins 21.SELECTED DRAWING: Figure 2 【課題】灯具ユニットのヒートシンクの冷却性能を向上させつつ、ヒートシンクのサイズを抑制した灯具ユニット、車両用灯具を提供する。【解決手段】灯具ユニットのヒートシンク２は、光源ユニットをヒートシンク２のベース部２３の裏面に載置するベース部２３と、ベース部２３の表面に形成された複数のフィンを備える。フィンは、互いに略平行に形成された複数の第一フィン２１と、第一フィン２１と非平行に形成されファン４の風を第一フィン２１に導く第二フィン２２を含む。【選択図】図２
