Abstract
A vehicular lamp includes: light sources; a first condensing optical system that condenses light beams from the light sources; and a second condensing optical system including an incident portion into which the condensed light beams by the first condensing optical system are incident, and an emission portion through which the incident light beams are outputted forward and which has a line-shaped emission surface. The incident portion has a refractive surface that refracts the light beams condensed by the first condensing optical system in a direction in which the light beams are condensed, and the refractive surface refracts the light beams so that condensing points of the light beams condensed by the first condensing optical system fall within a condensing range in which the light beams are outputted from the emission surface even when there is a positional deviation between the first and second condensing optical systems within a set tolerance.
