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.
