Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power supply device which can cool electronic components efficiently.SOLUTION: In a power supply device A1 comprising a plurality of electronic components 2 and a fan 4, and is constituted so that the plurality of electronic components 2 are cooled with air flowing through an elongated air duct 6 having an air feed inlet into which air discharged from the fan 4 is fed, the air feed inlet is movable in the longitudinal direction of the air duct 6. With such an arrangement, the air feed inlet can be moved to positions of the air duct 6 where heat absorption capacity is high. Consequently, temperature of specific one of the plurality of electronic components can be prevented from rising excessively, and the plurality of electronic components 2 can be cooled efficiently.
