[Problem] To provide a means for continuously manufacturing a superior, highly filler-filled, highly thermally-conductive thin sheet that satisfies various requirements such as thermal conductivity, electrical conductivity, an insulating property, a weight reduction property, mechanical characteristics, durability, design properties, moldability, mass productivity, and uniformity. [Solution] A mixture comprising organic polymer particles and highly thermally-conductive filler particles is uniformly dispersed using a grinder or mixer to obtain a powder composition, after which the powder composition is conveyed at a constant thickness between two belts of a double-belt press device. In the double-belt press device, the powder composition is continuously heated and pressurized at a specific pressure and a temperature equal to or greater than the load deflection temperature, melting point, or glass transition temperature of the organic polymer and then cooled and solidified, and thereby a highly filler-filled highly thermally conductive thin sheet is obtained. |
