PURPOSE: A method for coating a back sheet on a heat emitting sheet is provided to closely attach an expanded graphite sheet to the back sheet wherein a polyca sol is coated on the expanded graphite sheet, thereby increasing heat conductivity. CONSTITUTION: A heat emitting sheet includes an expanded graphite sheet(10). A back sheet(30) is coated on a first coating layer. A heat emitting sheet is wound on a tension roller. A first film roller(300) winds the back sheet on which the first coating layer is placed. A heat emitting sheet is rewound. |
