PROBLEM TO BE SOLVED: To provide a mechanism for fixing a heat sink which can be tightly joined with a CPU, and by which a decrease in radiation area of the heat sink due to the limit of an engaging member can be prevented, the heat sink can be rigidly amounted to the CPU, a heat pipe heat sink can be mounted, and blowing resistance of a fan can be reduced. SOLUTION: Grooves 214a are provided on both sides of side members of a heat sink 22 wherein grooves 211a are formed to fit a heat pipe 221, and the joint end 211 of the side edge of an elastic body 21 is fitted with the grooves 214a, and then a heat sink is joined and fixed onto a circuit board 25 on which a CPU base 24 provided with a CPU 23 is placed by a fixing means 212b by means of a spring. The heat sink equipped with a heat pipe is tightly fixed onto the CPU by the trigger action of the elastic body. COPYRIGHT: (C)2007,JPO&INPIT
