Patent ID: 8743546

Claim:
A sheet structure comprising: a plurality of carbon nanotube bundles, each of the carbon nanotube bundles comprising a plurality of carbon nanotubes, the plurality of carbon nanotubes being arranged, spaced from each other; a filling layer formed of an organic filling material and formed in gaps between the plurality of carbon nanotube bundles and in gaps between the carbon nanotubes in the respective carbon nanotube bundles, and supporting the plurality of carbon nanotube bundles; a first coating film formed over a first surface of the filling layer so as to be in contact with respective one ends of the plurality of carbon nanotube bundles and formed of a material having a higher thermal conductivity than the organic filling material; and a second coating film formed over a second surface of the filling layer so as to be in contact with respective other ends of the plurality of carbon nanotube bundles and formed of a material having a higher thermal conductivity than the organic filling material.
