Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production method for producing ultra low-sulfur fuel oil containing a monocyclic aromatic hydrocarbon with a high ratio by efficiently decomposing with a high decomposition rate. SOLUTION: Light cycle oil distilled by fluidized catalytic cracking which is a hydrocarbon oil highly containing an aromatic hydrocarbon is subjected to hydrodesulfurization treatment using a hydrodesulfurization catalyst in which at least one of groups 6, 8, 9, and 10 metals of the periodic table is carried by a refractory inorganic oxide carrier. Then, the resulting product is subjected to hydrocracking treatment using a hydrocracking catalyst in which at least one of groups 6, 8, 9, and 10 metals of the periodic table is carried by a refractory inorganic oxide carrier containing crystalline aluminosilicate.
