Abstract
A heat sink is attached to a semiconductor element functioning as an exothermic element, which is mounted on a circuit board and has a predetermined allowable power consumption, thereby cooling the semiconductor element. A semiconductor element having a lower allowable power consumption than the semiconductor element having the predetermined power consumption, which is hardly exposed to a cooling air flow cooled via the heat sink, is connected to a heat conductive auxiliary member connected at one end to the heat sink. Thus, the heat radiation efficiency of the semiconductor element having the lower allowable power consumption is enhanced.
