Abstract
A heat sink faces an exhaust port of a blower fan in use, and includes: a first plate-shaped portion; a second plate-shaped portion disposed in parallel with the first plate-shaped portion having a gap therebetween; a plurality of fins that stand up between the first plate-shaped portion and the second plate-shaped portion and are disposed side by side with a gap therebetween to define an air flow path between the fins, through which air flows from the exhaust port; and a protrusion that is disposed at a part of each fin including a center of the upright height, and protrudes into the air flow path.
