摘要： A present invention is a vehicle lamp provided with: an elongated light guide member provided in a lamp chamber, an incident end part being positioned below said member; and a light source provided in the lamp chamber so as to face the incident end part. The light guide member has: a light guide main part having an elongated shape in which one end is the incident end part, a prism part being provided along the longitudinal direction, the prism part causing a portion of the light incident from the incident end part to be emitted in the irradiation direction; and a flange part projecting from the light guide main part in the direction intersecting the irradiation direction. The flange part is provided with a reflecting surface that forms a depression angle with a projecting end face when viewed from the incident end part side within a prescribed range viewed in the longitudinal direction.
