Summary:PURPOSE: A heat radiation sheet is provided to effectively perform a dispersion function by releasing heat inside an electronic device to the outside. CONSTITUTION: A heat radiation sheet includes a graphite sheet. A graphite particle within the graphite sheet has directionality to a horizontal direction of the sheet. The graphite sheet comprises an aluminum tin oxide, an aluminum zinc oxide (AZO), an antimony tin oxide (ATO), an indium tin oxide (ITO), a boron nitride (BN), an aluminum nitride (AlN), and an additive which is a combination thereof in the inside. The content of the additive within the graphite sheet is 1-10 weight% to 100 weight% of the graphite sheet.
