摘要:
A heat-conductive sheet comprising a cured or semi-cured binder wherein a carbon fiber is orientated in the direction of the thickness of the heat-conductive sheet. This heat-conductive sheet exhibits a high anisotropic heat conductivity along the direction of the thickness thereof to thereby enable efficiently releasing heat from a heating element such as a semiconductor element or semiconductor package. Moreover, the heat-conductive sheet is excellent in not only heat resistance, durability and mechanical strength but also adherence to the heating element.
