PURPOSE: A heat sink fixing structure is provided to enhance a productivity, cut down a manufacturing cost, and easily attach/detach a heat sink to/from a PCB(Printed Circuit Board). CONSTITUTION: A PCB(1), to which an integrated circuit(2) is mounted, has fixing holes(3). A heat sink(4) is formed with supporting parts(5) which have fixing holes(6) corresponding to the fixing holes(3) of the PCB(1) respectively. In order to fix the heat sink(4) on the integrated circuit(2) mounted to the PCB(1), a fixing member(7) is inserted through the fixing holes(6) of the heat sink(4) and the fixing holes(3) of the PCB(1). The fixing member(7) has a fixing hook(8) at its lower end for preventing the fixing member(7) from separating from the fixing holes(3)(6). A spring(9) for modulating a fastening force of the fixing member(7) is provided around the fixing member(7).
