The present invention relates to a thermal spreading sheet with superior ductility and strength, and a method for manufacturing the same. One method for manufacturing the thermal spreading sheet according to the present invention comprises the steps of mixing graphite powder and binder; and applying the mixture of graphite powder and binder onto the surface of a reflective sheet to form the thermal spreading sheet with a predetermined thickness. The binder is preferable to contain polyurethane, acrylic or silicon. And, the mixture of graphite powder and binder is preferable to contain copper or silver. Another method for manufacturing the thermal spreading sheet according to the present invention comprises the steps of adding an acrylic resin into a fine graphite particle to form a nano-composite; and compressing the nano-composite at a high temperature. The method for manufacturing the thermal spreading sheet further comprises the step of adding a resin having high thermal conductivity into the nano-composite.
