Carbon-metal structure and method for manufacturing carbon-metal structure

A method for manufacturing a carbon-metal structure, comprising:

• forming on a substrate a carbon film layer containing a fibrous carbon;
• forming a brazing material layer on the carbon film layer formed on the substrate;
• brazing a metal pedestal to the carbon film layer with the brazing material layer interposed therebetween;
• and
• removing the substrate from the carbon film layer,
• wherein the brazing material layer has a multilayer structure having a first brazing material layer that is formed on a side of the carbon film layer and a second brazing material layer that is formed on a side of the metal pedestal and has a melting point lower than that of the first brazing material layer.

• brazing a metal pedestal to the carbon film layer with the brazing material layer interposed therebetween;
• and
• removing the substrate from the carbon film layer,
• wherein the substrate has on a surface thereof a texture having an average height of 1 μm to 100 μm and a height/spacing ratio of 1/5 to 5/1.

A method for manufacturing a carbon-metal structure, comprising:

• forming on a substrate a carbon film layer containing a fibrous carbon;
• forming a brazing material layer on a metal pedestal that supports the carbon film layer formed on the substrate;
• brazing a metal pedestal to the carbon film layer with the brazing material layer interposed therebetween;
• and
• removing the substrate from the carbon film layer,
