Beschreibung
Zusammenfassung:	Provided are a carbon catalyst, a battery electrode, and a battery each having excellent catalytic activity and excellent durability. The carbon catalyst includes iron, exhibits a weight reduction ratio in the temperature range from 200°C to 1,200°C of 12.0 wt% or less measured by thermogravimetric analysis in a nitrogen atmosphere, and has a carbon structure that exhibits, in X-ray absorption fine structure analysis of a K absorption edge of the iron, the following (a) and/or (b): (a) a ratio of a normalized absorbance at 7,130 eV to a normalized absorbance at 7,110 eV is 7.0 or more; and (b) a ratio of a normalized absorbance at 7,135 eV to a normalized absorbance at 7,110 eV is 7.0 or more.
