    • PROBLEM TO BE SOLVED: To provide a spherical mesoporous carbon having a center pore diameter of >2 nm, and to provide a method for producing the carbon. SOLUTION: The spherical mesoporous carbon is composed of carbon nanorods having an interval of >2 nm. The method for producing the spherical mesoporous carbon includes: a step of producing precursor particles, in which a silica source material that forms the skeleton of a spherical mesoporous silica with a nitrogen-containing compound having a nitrogen-containing functional group, by molar ratio of 99:1 to 80:20 and the mixture is copolymerized in the presence of a surfactant to obtain precursor particles comprising the spherical mesoporous silica having the mesopores filled with the surfactant; a step of increasing diameters, in which diameters of the mesopores are increased to obtain the center pore diameter in the diameter distribution of ≥4 nm; a step of removing organic substances, in which organic substances in the meropores are removed; a carbonization step of introducing a carbon source into the mesopores to carbonize; and a step of removing silica of dissolving and removing the silica from the spherical mesoporous silica having the mesopores filled with carbon.
