    摘要： Provided is a carbon catalyst having an improved catalytic activity, a production method therefor, and an electrode and a battery which use the carbon catalyst. The carbon catalyst is obtained by carbonizing a raw material including an organic substance containing a nitrogen atom and metals, and includes iron and/or cobalt, and copper as the metals. Further, the carbon catalyst has a crystallinity of 41.0% or less, which is determined by X-ray diffractometry, a nitrogen atom-to-carbon atom ratio of 0.7 or more, which is determined by X-ray photoelectronic spectrometry, and an oxygen reduction-starting potential of 0.774 V (vs. NHE) or more.
