<p>PURPOSE: A three-kind-complex-metallic-oxide catalyst for manufacturing dimethyl carbonate, a manufacturing method thereof, and a manufacturing method of dimethyl carbonate using the same are provided to be manufacture dimethyl carbonate with high yield in a milder reaction condition when being used as a catalyst for the synthesis of dimethyl carbonate from urea and methanol. CONSTITUTION: A three-kind-complex-metallic-oxide catalyst for manufacturing dimethyl carbonate comprises a first metal oxide, a second metal oxide, and a third metal oxide. The first metal oxide is a zinc oxide. The second metal oxide is a cerium oxide. The third metal oxide is selected from a gallium oxide, zirconium oxide, cobalt oxide, yttrium oxide, and lanthanum oxide.
