<P>PROBLEM TO BE SOLVED: To provide a heat radiation structure which enhances heat radiation on a heat radiation surface and improves heat radiation efficiency. <P>SOLUTION: A heat radiation structure is composed of a cooling element 5 having an endotherm surface 6 joined to a surface of an electronic element 3 and a pedestal 11 which is connected with a heat radiation surface 7 side of the cooling element 5 and from which heat from the electronic element 3 is radiated. The pedestal 11 is composed of a metal plate member 13 which is larger than the area of the heat radiation surface 7 of the cooling element 5 and smaller than the superficial area of a substrate 2 and a heat conductive sheet 15 which is joined to the plate member 13 and is formed so as to be larger than the area of the heat radiation surface 7 of the cooling element 5 and smaller than the superficial area of the substrate 2. One surface of the heat conductive sheet 15 is joined to the plate member 13 and the other surface is joined to the heat radiation surface side of the cooling element 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
