PURPOSE: A hybrid alloy catalyst manufactured by a multi-melt-infiltration process and a manufacturing method of the alloy catalyst are provided to easily support two or more alloy nanoparticles in a porous oxidation metal support. CONSTITUTION: A manufacturing method of a hybrid alloy catalyst includes the steps of: mixing two or more metal salts and a porous support; fusing the metal salts by a multi-melt-infiltration process; and alloying the metal salts in the porous support by a high temperature plasticizing process. The melting point of the metal salts are in the range of 20-130°C.
