Claim Text:
1. A vehicle lamp comprising: a semiconductor light emitting device; a thermally conductive portion which is in contact with the semiconductor light emitting device; a heatsink configured to dissipate a heat generated by the semiconductor light emitting device; and a housing in which the semiconductor light emitting device, the thermally conductive portion and the heatsink are accommodated, wherein the heatsink comprises: a base which is in contact with the thermally conductive portion; and a plurality of plate fins which are arranged at intervals to protrude from the base, each of the plate fins comprising a plate surface which faces the plate surface of an adjacent one of the plate fins and which upwardly extends in a direction along the base, the plate fins being accommodated within the housing, wherein the housing comprises an inner surface which is arranged directly above the plurality of plate fins and which is oblique with respect to a vertical direction; whereby air flowing between the plate fins is directed toward the inner surface, wherein the base comprises: a front surface to which the thermally conductive portion is fixed; and a rear surface from which the plurality of plate fins rearwardly protrudes, wherein the rear surface of the base is downwardly oblique with respect to the vertical direction.
