Abstract: Disclosed is a method for producing a thermally conductive thin film for protecting elements and the like integrated inside an electronic device such as a smartphone from heat. A method for using synthetic graphite powder to produce a thin film that has excellent thermal conductivity compared to existing natural graphite thin films or metal thin films and can be produced at lower cost than existing synthetic graphite thin films obtained from polyimide or the like may be provided.

Abstract: The present invention relates to a thermally conductive thin sheet for protecting an element, etc. integrated in an electronic device from heat, and an article comprising the same. As the thermally conductive thin film sheet has a thermally conductive filler layer formed on both surfaces of a thermally conductive adhesive film having a composite filler, the thermally conductive thin film sheet has excellent tensile strength and flexibility and thus is easy to handle while having a high fill factor of the thermally conductive filler. Accordingly, heat generated during use can be effectively removed by applying the thermally conductive thin film sheet to various articles such as electronic devices, illumination equipment, etc., in which a light emitting source such as an LED, an OLED, etc. is adopted or IC chips are highly integrated.
