To provide a vehicular lighting fixture capable of forming an irradiation pattern with a desired light distribution while suppressed from increasing in size.SOLUTION: A vehicular lighting fixture 10 comprises: a plurality of light sources (21, 22 and 23); a condenser lens 12 which receives from an incidence surface 34 and emits from an emission surface 35 lights from the plurality of light sources (21, 22 and 23) to converge them; a light shield member (13) which is provided with a plurality of a translucent parts (28) transmitting in part the lights converged by the condenser lens 12; and a projection lens 14 which projects the light passed through the light shield part (13) to form an irradiation pattern Pi having a plurality of irradiation patterns Di corresponding to the plurality of translucent parts. The light sources (21, 22 and 23) are provided individually corresponding to the translucent parts, and the condenser lens 12 has a plurality of condenser lens parts (31, 32 and 33), individually corresponding to the translucent parts, put one over another.SELECTED DRAWING: Figure 3 【課題】大型化することを抑制しつつ、所望の配光分布の照射パターンを形成できる車両用灯具を提供する。【解決手段】車両用灯具１０は、複数の光源（２１、２２、２３）と、複数の光源（２１、２２、２３）からの光を入射面３４から入射させて出射面３５から出射して集光する集光レンズ１２と、集光レンズ１２で集光された光を部分的に通す複数の透光部（２８）が設けられた遮光部材（１３）と、遮光部材（１３）を通した光を投影することにより、複数の透光部に対応する複数の照射図柄Ｄｉを有する照射パターンＰｉを形成する投影レンズ１４と、を備える。光源（２１、２２、２３）は、透光部に個別に対応して設けられ、集光レンズ１２は、透光部に個別に対応する複数の集光レンズ部（３１、３２、３３）が重ねられている。【選択図】図３
