PROBLEM TO BE SOLVED: To provide an inexpensive joining method for a carbon based copper composite material and ceramics or for a carbon based copper composite material and copper which can enhance adhesiveness. SOLUTION: Materials to be joined are heated to 900°C in the nitrogen gas atmosphere. Mg powder 12 is sublimed and turned into Mg (a gas). Then, the Mg reacts with the atmosphere N<SB>2</SB>and generates Mg<SB>3</SB>N<SB>2</SB>. The Mg<SB>3</SB>N<SB>2</SB>has the strong reduction action and exerts the action to remove an oxide film. Heating is conducted in an atmosphere of nitrogen, which is inexpensive and has no danger of explosion. Accordingly, costs for joining can be significantly reduced. COPYRIGHT: (C)2004,JPO&NCIPI
