An image pickup apparatus which is capable of efficiently cooling itself using a general-purpose ice pack so as to be able to shoot without heating an exterior surface thereof to a high temperature even under a high temperature environment. A cooling unit of the image pickup apparatus has a first duct having an inlet, a second duct connected to the first duct, and a third duct having an outlet and connected to the second duct. The second duct is thermally connected to a first heat source, the third duct is thermally connected to a second heat source that generates a larger amount of heat than the first heat source, and air taken in through the inlet passes through the first duct, the second duct, and the third duct in this order and is discharged through the outlet.
