Abstract
A carbon catalyst has improved catalytic activity, and an electrode and a battery include the carbon catalyst. A carbon catalyst includes a metal and phosphorus atoms, wherein a ratio of a concentration (atomic %) of the phosphorus atoms exhibiting a peak having a peak top within a range of 132.5±0.3 eV and having a full width at half maximum of 2.0±0.5 eV, which is obtained by peak separation of a phosphorus atom P2p peak, with respect to a concentration (atomic %) of carbon atoms in X-ray photoelectron spectroscopic measurement is 0.0005 or more.
