摘要： Provided are a diamond composite material which is excellent in thermal conductivity, suitable as a material for a heat radiating member, and dense, the heat radiating member, and a method for producing a diamond composite material that can productively produce a diamond composite material which is excellent in wettability between diamond and metal and dense. The diamond composite material includes: a coated diamond particle including a diamond particle and a carbide layer covering a surface of the diamond particle and including an element of group 4 of the periodic table; and silver or a silver alloy binding such coated diamond particles together, with an oxygen content of 0.1 mass% or less.

摘要： Provided are a heat radiating member allowing a semiconductor element to be bonded with high bondability to a surface of a composite portion composed of a composite material, and a method for producing the same. A heat radiating member includes: a composite portion composed of a composite material which contains particles of a satisfactorily thermally conductive material in a metal matrix; and a metal layer formed on at least one surface of the composite portion and composed of a metal. A method for producing a heat radiating member includes: a preparation step to prepare a composite material which contains particles of a satisfactorily thermally conductive material in a metal matrix; a powder arrangement step to dispose a metal powder composed of metal particles on at least one surface of the composite material; and a heating step to heat the composite material and the metal powder, with the metal powder disposed on the composite material, to form a metal layer composed of a metal of the metal powder on a composite portion composed of the composite material.
