Carbon-based material, an electrode catalyst, electrode, gas diffusion electrode, an electrochemical device, a fuel cell, and method of producing a carbon-based material

Carbon-based material according to the present invention, a non-metal atom such as a nitrogen atom, and a metal atom is doped. Also, near the coordinate bond distance the K-edge EXAFS of metal atoms in the radial distribution function obtained by Fourier transform, to the intensity B of the maximum peak appearing near the metal bonding distance of the metal atom, the metal atom and non-metal atom the ratio a / B of the maximum peak intensity a appearing in is 4.0 or more. However, if the metal atom is platinum atom, the ratio A / B in the radial distribution function obtained by LIII edge EXAFS of platinum atoms by Fourier transform it is 4.0 or more.
