Abstract
A heat radiation sheet including: a heat radiation layer that is formed in the form of a nano-web having a plurality of pores by electrospinning a spinning solution that is obtained by mixing a polymer material and a solvent, or the polymer material, a heat conductive material, and the solvent; and an adhesive layer that is laminated on one surface or both surfaces of the heat radiation layer, and that is formed in the form of the nano-web by electrospinning an adhesive material that is obtained by an adhesive, the heat conductive material, and the solvent.
