To provide a lamp unit which can form an irradiation pattern in the vicinity of a vehicle on which the lamp unit is mounted while suppressing an increase in inclination in a condition of being mounted on the vehicle.SOLUTION: A lamp unit 20 comprises: a plurality of light sources (34, 35); a condenser lens 23 for condensing light from the plurality of light sources (34, 35); a light shielding member (24) having a plurality of slit parts 46 that allow the light condensed by the condenser lens 23 to partially pass therethrough; and a projection lens 25 which forms an irradiation pattern Pi having a plurality of irradiation figures Di corresponding to the plurality of slit parts 46 by projecting the light which has passed through the light shield member (24). The plurality of light sources (34, 35) are provided above a projection lens optical axis AI of the projection lens 25, and the plurality of slit parts 46 are provided above the projection lens optical axis AI.SELECTED DRAWING: Figure 6 【課題】車両に搭載された状態での傾きの増大を抑制しつつ、搭載された車両の近傍に照射パターンを形成することのできるランプユニットを提供する。【解決手段】複数の光源（３４、３５）と、複数の光源（３４、３５）からの光を集光する集光レンズ２３と、集光レンズ２３で集光された光を部分的に通す複数のスリット部４６が設けられた遮光部材（２４）と、遮光部材（２４）を通した光を投影することにより、複数のスリット部４６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２５と、を備えるランプユニット２０である。複数の光源（３４、３５）は、投影レンズ２５の投影レンズ光軸Ａｌよりも上方に設けられ、複数のスリット部４６は、投影レンズ光軸Ａｌよりも上方に設けられている。【選択図】図６
