Disclosed is a macrocyclic organic compound-based reduction catalyst having high oxygen-reducing activity. Specifically disclosed is an oxygen reduction catalyst obtained by loading a conductive carrier with a porphyrin complex represented by the following formula (I). (I) [In the formula, each R independently represents a hydrogen atom, an alkyl group having 1-6 carbon atoms, a halogen atom, an amino group, a hydroxyl group, a nitro group, a phenyl group or a cyano group, or adjacent Rs may combine together to form a methylene chain having 2-6 carbon atoms or an aromatic ring; each R' represents a thienyl group; and M represents a metal atom selected from the group consisting of Cu, Zn, Fe, Co, Ni, Ru, Pb, Rh, Pd, Pt, Mn, Sn, Au, Mg, Cd, Al, In, Ge, Cr and Ti. In this connection, M may be bonded with a halogen atom, an oxygen atom, -OH, a nitrogen atom, NO or =CO. |
