11. A porous electrode comprising: a porous carbon, wherein the porous carbon comprises at least one type of metal-nonmetal element bond represented by M-R, in which M represents a metal element of Groups 4 to 15, and R represents a nonmetal element wherein the nonmetal element represented by R is carbon element constituting the porous carbon, or a nonmetal element of Groups 14 to 16, other than the carbon element, linked to the carbon element constituting the porous carbon via a covalent bond, wherein when R is a nitrogen, the nitrogen is derived from an organic compound comprising R selected from organic polymers having complex aromatic ring, the M-R is at least one selected from the group consisting of Sb—C, Co—C, Ag—N, Ni—S, Ni—N, Co—N, Co—S, Mo—N, Nb—N, Ni—C, Pb—N, and Sb—N.
