Abstract
A carbon catalyst which has high catalytic activity and can achieve high catalyst performance is provided. The carbon catalyst comprises nitrogen. The energy peak area ratio of the first nitrogen atom whose electron in the 1s orbital has a binding energy of 398.5±1.0 eV to the second nitrogen atom whose electron in the 1s orbital has a binding energy of 401±1.0 eV (i.e., the value of (the first nitrogen atom)/(the second nitrogen atom)) of the nitrogen introduced into the catalyst is 1.2 or less.
