Abstract
A thermally conductive sheet includes a resin composition including a silicone rubber, and thermally conductive fillers that are anisotropic, the thermally conductive fillers being dispersed in the silicone rubber. A content of the thermally conductive fillers in the resin composition is 52% by volume or more and 75% by volume or less. Major axes of the thermally conductive fillers are oriented in a thickness direction of the thermally conductive sheet, and a ratio of a peak intensity of a (002) plane to a peak intensity of a (100) plane in a spectrum measured from the thickness direction by an X-ray diffraction method is 0.31 or less.
