Abstract: PROBLEM TO BE SOLVED: To provide a heat transfer board having an improved heat transferring performance with a diamond used as a heat transfer material, and to provide an economical method for manufacturing the same. SOLUTION: The heat transfer board is a plate material with the single crystal grains of a diamond with even size showing prominent crystal plane having an average grain diameter of 1.0 mm or less bonded in single layer in plane by a heat-resisting bonding agent and the surface occupancy factor of the diamond on each surface (plate surface) of the plate material is 25% or more (1). The method of manufacturing the heat transfer board comprises the steps of filling the single crystal grain of diamond with even size showing prominent crystal plane having an average grain diameter of 1.0 mm or less in a mold having a plane bottom face, infiltrating organic adhesive agent between grains, forming a diamond layer or grain assembly by fixing the diamond grains, and then removing the mold and the adhesive agent from the diamond layer surface by polishing the surface of the diamond layer (2). The occupancy ratio and the surface roughness on the surface of the diamond layer are respectively 25% or more and Ra 0.5 μm or less. COPYRIGHT: (C)2004,JPO
