PURPOSE: To improve heat transfer efficiency by attaching a copper porous body or a copper alloy porous body to the main body of a conductive metal integrally.
CONSTITUTION: The sintered body of a metal is constituted of a three-dimensional reticulated structure while said sintered body is attached to the surface of a metallic plate having the same material or inserted between metallic plates or attached to the inside and outside of a metallic pipe integrally to sinter them. In this case, the three-dimensional reticulated structural body, to which copper powder, copper oxide powder or metallic powder containing copper or copper oxide is attached in gas phase, is inserted into and engaged with the inner surface of a metallic copper tube 3, to which copper powder, copper oxide powder or metallic powder containing copper is attached to the inner or outer surface or both surfaces thereof, or said structural body is wound while pressing it against the outer surface of the copper tube 3 or otherewise the structural bodies are fitted and wound into and around the tube 3 simultaneously, and subsequently, sintering is effected whereby a heat conductive member having the three-dimensional reticulated structural body 4 of a metal can be manufactured. According to this method, a heat transfer efficiency can be improved.
