The present invention relates to a manufacturing method of conjugated diene. According to the present invention, a manufacturing method of conjugated diene such as butadiene, or the like, through a contact oxidative dehydrogenation reaction of mono-olefin such as n-butene, or the like can effectively remove byproducts such as acrolein, butenone, benzaldehyde, and the like, during a dehydration process after a cooling process without using a desiccant. The manufacturing method comprises the following steps of: a) manufacturing a product gas including butadiene by oxidative dehydrogenation of a raw gas including n-butene; b) cooling the product gas, and manufacturing an organic solution by making the product gas absorb to an organic solvent; and c) obtaining crude butadiene by degassing and stripping the organic solution.
