Patent ID: 8691368

Claim:
A thermally and electrically conductive sheet configured to discharge heat from a heat discharging body, the heat being generated from a heat emitting body, and to prevent electrostatic discharge due to charging of the heat emitting body, the thermally and electrically conductive sheet comprising: an electrically conductive layer located on the heat emitting body, the electrically conductive layer having a central portion that contacts the heat emitting body and a peripheral portion that contacts the heat discharging body; and a thermally conductive polymer layer located between the central portion of the electrically conductive layer and the heat discharging body and comprising a polymer matrix and a filler in fiber form; wherein the filler is oriented in a direction of a thickness of the thermally conductive polymer layer, wherein the polymer matrix and the filler contact the electrically conductive layer and the heat discharging body to transfer the heat from the heat emitting body to the heat discharging body, and wherein the electrically conductive layer allows a current to flow from the heat emitting body to the heat discharging body due to the contact of the peripheral portion of the electrically conductive layer with the heat discharging body.
