To provide a vehicular lighting fixture capable of achieving surface light emission which is uniform when viewed from any direction, without causing increase in the number of components.SOLUTION: A tail lamp (vehicular lighting fixture) 1 comprises by storing at least an LED 5 which is a light source, a reflector 7 which reflects the light emitting from the LED 5 in a predetermined direction, and an inner lens 8 for transmitting the light reflected by the reflector 7, in a lamp chamber 4 defined by a housing 2 and an outer lens 3 for covering the opening. In the reflector 7, an extension part 7A extending further downward than a bottom surface 7b is formed, and a space S is formed in the extension part 7A by covering a lower surface opening of the extension part 7A with a substrate 6 on which the LED 5 is mounted, and the LED 5 is stored at the bottom part of the space S, and the surface of the extension part 7A connected to a reflection surface 7a of the reflector 7 is made to be a reflection surface 7c.SELECTED DRAWING: Figure 2 【課題】部品点数の増加を招くことなく、どの方向から見ても均一な面発光を実現することができる車両用灯具を提供すること。【解決手段】ハウジング２とその開口部を覆うアウタレンズ３によって画成された灯室４内に、少なくとも光源であるＬＥＤ５と、該ＬＥＤ５から出射する光を所定の方向に反射させるリフレクタ７と、該リフレクタ７によって反射した光を透過させるインナレンズ８を収容して成るテールランプ（車両用灯具）１において、前記リフレクタ７に、その底面７ｂよりも下方に延びる延長部７Ａを形成し、前記ＬＥＤ５が実装された基板６で前記延長部７Ａの下面開口部を覆って該延長部７Ａ内に空間Ｓを形成し、該空間Ｓ内の底部に前記ＬＥＤ５を収容するとともに、前記延長部７Ａの前記リフレクタ７の反射面７ａに連なる面を反射面７ｃとする。【選択図】図２
