    Abstract: A rolled graphite sheet includes a rod-shaped body and a graphite sheet having a length of 1 m or more and a width shorter than the length. The graphite sheet is wound around the rod-shaped body and is rolled in a length direction. When a length direction-end of the graphite sheet is pulled with a force of 1.5 N/cm in a direction parallel to a tangent of a cross-sectional circle of the rolled graphite sheet while fixing the rod-shaped body, the end moves 5 mm or less in the direction parallel to the tangent of the circle.

    Abstract: Provided are (i) a heat transport structure which is excellent in heat transfer efficiency and (ii) a method of producing such a heat transport structure. The heat transport structure in accordance with an embodiment of the present invention includes: a first thermally conductive material in which through holes are formed; and second thermally conductive materials which are fitted in the respective through holes in a perpendicular direction which is a direction perpendicular to a surface direction, a thermal conductivity which the first thermally conductive material exhibits in the surface direction being higher than a thermal conductivity which the first thermally conductive material exhibits in the perpendicular direction, each of the second thermally conductive materials being held by an inner surface of a corresponding one of the through holes and having fitting strength of not less than 0.5 N/mm per unit circumference of the corresponding one of the through holes.

    Abstract: Provided is a long and large-area graphite film having improved thermal diffusivity and flex resistance, and accompanied by ameliorated ruffling. According to a method for producing a graphite film, in which graphitization of a heat-treated film consisting of a carbonized polymer film is carried out in a state being wrapped around an internal core, the method being characterized in that a heat treatment is executed by controlling distance(s) between the internal core and the film, and/or between the layers of the film, a graphite film accompanied by significantly ameliorated ruffling can be obtained.

    Abstract: A re-forming process is carried out in which a material graphite film is heat-treated to not less than 2000° C. while the material graphite film is being pressured. Through the re-forming process, sag of a graphite film is controlled. By using, during the re-forming process, a plurality of inner cores having respective different surface states, it is possible to produce a graphite film having two or more sag forms which have respective effects.
