Abstract:
1. A high thermal conduction insulator which is used with one surface thereof in contact with a facing member for radiating heat of the facing member from the other surface opposite to the one surface, comprising: a substrate composed of a resin exhibiting electrical insulating properties, and having one surface and the other surface opposite to said one surface of said substrate; and a diamagnetic material powder, and a paramagnetic material powder including ferromagnetic material, which are included in said substrate, wherein said diamagnetic material powder is oriented from said one surface of said substrate toward said the other surface thereof as clusters, each being composed of a plurality of diamagnetic material particles of said diamagnetic material powder, which are joined together like a chain, and said paramagnetic material powder including said ferromagnetic material mainly exists on the side of said the other surface of said substrate, thereby forming a heat radiating layer.
