ABSTRACT:
The thermally conductive body for use by being placed between a heat generating body and a heat radiating body, in which the body is molded from a thermally conductive polymer composition. The thermally conductive polymer composition contains a polymer matrix and a thermally conductive filler. At least part of the thermally conductive filler is formed in the shape of fibers and oriented in a certain direction. In the body, ends of the thermally conductive filler formed in the shape of fibers are exposed on the outer surface intersecting the direction of the orientation. Protrusions extending along the outer surface are formed thereat. In case, the body is placed between the heat generating body and the heat radiating body so that the outer surface contacts at least one of the heat generating body and the heat radiating body.
