Abstract:
Provided is a method of manufacturing a heat conductive sheet that itself is imparted with stickiness and has reduced heat resistance due to improved adhesion to a heat generator and a heat dissipater and that may be fixed provisionally without the need for using an adhesive agent or the like. The method includes the steps of molding a heat conductive resin composition, which includes heat conductive fillers and a binder resin, into a predetermined shape and curing the heat conductive resin composition to obtain a molded product of the heat conductive resin composition, cutting the molded product into sheets to obtain a molded product sheet, and coating an entire surface of a sheet main body (7) with an uncured component (8) of the binder resin oozing from the sheet main body (7).
