<P>PROBLEM TO BE SOLVED: To provide a high-performance heat radiation sheet having flexibility in the thickness direction although it is made of a material exhibiting ultrahigh thermal conductivity exceeding 100 W/mK in the thickness direction of the sheet, and capable of reducing contact thermal resistance by being interposed between a heating element and a radiator. Ž<P>SOLUTION: In this heat-conducting sheet with graphite oriented in the thickness direction which has a thickness ≤5 mm, graphite films 1 each having a thickness ≤1 mm are laminated through organic layers 2 so as to orient the crystal plane of the graphite in the thickness direction; and the ratio of graphite area/organic layer area observed from the surface direction of the sheet is 75/25 to 10/90. This application also provides a manufacturing method of the heat-conducting sheet with graphite oriented in the thickness direction which has high thermal conductivity in the thickness direction, and is formed by cutting, in a thickness ≤5 mm at a plane forming an angle ≥45° with respect to the crystal plane of the graphite, a graphite laminated body composed by laminating the graphite films 1 each having a thickness ≤1 mm through the organic layers 2 by a superposing or winding means.
