Abstract

A portable electronic apparatus comprises a box-shaped housing. A metal-made frame is contained in the housing. The frame supports a circuit board. A circuit element, generating heat while operating, is mounted on the circuit board. A fan is contained in the housing so as to guide cooling air to the circuit element. The frame has a cooling air passage to guide cooling air thereto by the fan. The cooling air passage has a heat receiving part where heat of the circuit element is transmitted, and the heat receiving part is cooled by cooling air flowing to the cooling air passage.
