Abstract
A carbon-based material according to the present invention contains dopant atoms of metal and non-metal such as nitrogen. In a radial distribution function obtained by Fourier transform of a K-edge EXAFS of the metal, a ratio of 'A' to 'B' is equal to or more than 4.0, wherein “A” denotes an intensity of the highest one of peaks around a distance equal to a coordinate bond length between atoms of the metal and the non-metal and “B” denotes an intensity of the highest one of peaks around a distance equal to a metallic bond length between atoms of the metal. Note that when the metal is platinum, in a radial distribution function obtained by Fourier transform of an LIII-edge EXAFS of the platinum, a ratio of “A” to “B” is equal to or more than 4.0.
