The present invention relates to the manufacturing method of the electrocatalyst including the macrocyclic compound which the chemically can be combined in the porous carbon support material, and the catalytic substance of the metal form of at least one type and carbon support and form the composite in which 1 of the metal or the metals has the metal ion, and it is the porosity and (1) the method very includes the step of providing the mold (templated) serving of in manufacture pore structure inducing agent (pore structure directing agent) of the mold carbon substrate (templated carbon substrate), the step of mixing (2) mold with the catalytic substance, and at least one precursors of carbon and macrocyclic compound, and the step of exposing the mixture of the precursors and mold to the ashing of (3) precursor reacting and transforming the mixture to the carbonized template synthesis water and the carbon part of the synthesized material chemically unites the metal or the metals with the macrocyclic compound existing in the above-mentioned carbonized template synthesis water within the composite had. The step of providing the mold (templated) serving of in manufacture pore structure inducing agent (pore structure directing agent) of the mold carbon substrate (templated carbon substrate) is the electric conductance. The invention relates to moreover, the electrocatalyst for the electrochemical reaction, the method for manufacturing the membrane electrode assembly using such electrocatalyst, and the fuel cell using such electrocatalyst.
