A manufacturing method of butadiene includes an electrolytic reduction process that produces ethylene and oxygen from carbon dioxide and water as a raw material by electrolytic reduction, a butene producing process that produces butene by dimerizing the ethylene produced in the electrolytic reduction process, a mixing process that prepares a mixed gas by mixing the oxygen produced in the electrolytic reduction process, the butene produced in the butene producing process, and air, and a butadiene producing process that produces butadiene by heating the mixed gas and oxidatively dehydrogenating the butene, wherein carbon dioxide by-produced in the butadiene producing process is used as a portion of the raw material in the electrolytic reduction process.
