Abstract:
A heat dissipating structure for positioning between an electronic component and a heat dissipating component, the heat dissipating structure comprisinga graphite sheet; and a layer comprising a heat conducting material provided on at least one surface of said graphite sheet, wherein said heating conducting material has no fluidity at room temperature when said electronic component is not operating, but undergoes a reduction in viscosity, softens or melts, under influence of heat generated during operation of said electronic component; said heat conducting material comprises a silicone resin, which forms a matrix phase, and a heat conducting filler; and said silicone resin comprises T units represented by the formula RSiO3/2 and D units represented by the formula R2SiO, where R stands for a monovalent hydrocarbon group of 1 to 10 carbon atoms, at a ratio of T units to D units ranging from 10:90 to 90:10.
