<P>PROBLEM TO BE SOLVED: To provide electronic equipment wherein it is possible to equalize the temperature rise value of each element to reduce temperature variation from element to element without hindering space saving or size reduction. Ž<P>SOLUTION: Direct-current input voltage from an input-side circuit is converted into alternating-current voltage by switching operation of a switching element 7. This alternating-current voltage is converted into direct-current output voltage and outputted through an output-side circuit. In this equipment, the following are installed on a one-piece heat sink 41: an input-side heater element 21 comprising the input-side circuit; the switching element 7; and an output-side heater element 22 comprising the output-side circuit. It is more desirable that these elements 21, 7, 22 are arranged in the order of the input-side heater element 21 to the switching element 7 to the output-side heater element 22.
