PROBLEM TO BE SOLVED: To improve a heating efficiency without increasing a heat sink. SOLUTION: An electronic apparatus comprises an external heat sink 5b provided on an outer surface of a back plate 1a of a housing 1, a thermal conductive rubber sheet 6 provided on an inner surface of the plate 1a, and a pair of power source units 2 provided detachably from below a sheet of a front surface side in the housing 1. The units 2 each has a power source module 3 or the like in a case 4, an internal heat sink 5a mounted to cool the module 3 so that the sink 5a is positioned fixedly to a position brought into contact with the sheet 6 when the unit 2 is inserted into the housing 1.
