The vehicular lamp (10) is provided with: a main light source (11) for emitting light for forming a predetermined irradiation pattern; an optical member (14) for forming the irradiation pattern by causing the light emitted from the main light source (11) to advance forward in an irradiation direction; a heat dissipation member (12) for releasing heat from the main light source (11) to the outside; and a light guide member (30) for guiding light from an auxiliary light source (20) disposed as a separate body from the main light source (11). The heat dissipation member (12) is provided with an opening part (22) where a mounting surface (12c) on which the main light source (11) is provided in the heat dissipation member (12) is open, and the light guide member (30) guides the light from the auxiliary light source (20) toward the mounting surface (12c) side through the opening part (22).
