Abstract

The present invention provides a nitrogen-containing carbon material characterized in that it satisfies a specific relational expression between the number ratio of nitrogen atoms to carbon atoms and the number ratio of hydrogen atoms to carbon atoms and has peaks in specific regions in the X-ray diffraction and in the laser Raman spectrum. The nitrogen-containing carbon material of the present invention can be produced by carbonizing azulmic acid in an inert gas atmosphere, and it is useful as an electrode material or the like because it has a high nitrogen content and a low hydrogen content.
