Abstract

A method of producing a heat conductive sheet without using a high-cost magnetic field generator. This is achieved by allowing a large amount of a fibrous filler to be contained in a thermosetting resin composition, so that good heat conductivity is obtained without applying a load that may interfere with the normal operation of a heat generating body and a radiator to the heat generating body and the radiator when the heat conductive sheet is disposed therebetween. The method includes: a step (A) of dispersing a fibrous filler in a binder resin to prepare a heat conductive sheet-forming composition; a step (B) of forming a molded block using the prepared heat conductive sheet-forming composition according to an extrusion molding method or a die molding method; a step (C) of slicing the formed molded block into a sheet; and a step (D) of pressing the sliced surface of the obtained sheet.
