Patent ID: 7439475

Claim:
A thermally conductive body for placement between a heat generating body and a heat radiating body, the thermally conductive body being molded formed from a thermally conductive polymer composition; the thermally conductive polymer composition comprising: a polymer matrix; and a thermally conductive filler, in which at least part of the thermally conductive filler is formed in the shape of fibers, and oriented in a certain direction, wherein an outer surface of the thermally conductive body intersects said direction and contacts at least one of the heat generating body and the heat radiating body at the time of use, wherein the thermally conductive filler formed in the shape of fibers includes: ends that are exposed on the outer surface and have protrusions extending along the outer surface, said protrusions having a cross-section perpendicular to a fiber axial direction which is larger than the cross-section of the fiber that is within the polymer matrix.
