An automotive lamp includes an LED as a light source, a heatsink for radiating heat produced by the LED, the heatsink including a plurality of plate fins installed upright on base parts and a plurality of ventilation passages formed between the plate fins, a centrifugal fan for performing the forced air cooling of the plate fins by sending air through the ventilation passages of the heatsink, the centrifugal fan having air inlets in an axial direction for drawing air in, a left-side air outlet and a right-side air outlet for discharging air in left-right directions perpendicular to the axial direction, and a lamp housing for housing the LED, heatsink and centrifugal fan. The plate fins of the heatsink are formed such that the entrance of at least one of a plurality of ventilation passages faces the left-side air outlet and the right-side outlet of the centrifugal fan.
