The invention provides an air cooling duct and a cooling apparatus which can effect ventilation and cooling with certainty while suppressing noise. The cooling air duct is provided on a wall of a housing, in which a heat source is accommodated, and inducts external air into the housing or vents air in the housing to the outside of the housing in order to cool the inside of the housing. The cooling air duct defines an air path for communicating the inside and the outside of the housing with each other and further defines an expansion chamber formed on the air path. The cooling apparatus includes the cooling air duct. The cooling air duct and the cooling apparatus can be used principally to cool the inside of a housing of an electronic apparatus such as a computer or a communication apparatus.
