PROBLEM TO BE SOLVED: To secure the coherency between heat generating electronic components and a heat sink, and at the same time to separate a soldering process from a heat sink assembly one in a heat sin device used for various electronic equipment. SOLUTION: A folding section 3a is provided at one end of the heat sink 3, is brought into contact with pad rubber 5 of a PWB 1, and at the same time is screwed to a spacer 7 fixed onto the PWB 1 at nearly the middle point between the heat generation electronic components 2 and the folding section 3a, thus securing the coherency between the heat generation electronic components 2 and folding section 3a for efficiently transferring heat, and at the same time assembling the heat sink 3 after the heat generation electronic components 2 are mounted onto the PWB 1 by solder.
