Zusammenfassung:	A lamp unit forms an irradiation pattern having a desired brightness distribution while efficiently using light from a light source. In the lamp unit, a light source unit including light sources, a condenser lens, a light shielding member (shade), and a projector lens are arrayed along a lamp unit axis. An incident surface has a curved incident surface section facing the light sources and an annular incident surface section surrounding the curved incident surface section. The condenser lens has a reflective surface surrounding the curved incident surface section. The light shielding member (shade) is disposed such that a light shielding reference point coincides with a lamp unit axis. The light sources are disposed with an emission light axis positioned above the lamp unit axis in the vertical direction. The condenser lens is disposed such that condenser lens axes are positioned above the lamp unit axis in the vertical direction.
