Method for producing hydrocarbon oil

This method for producing a hydrocarbon oil obtains a hydrocarbon oil containing a hydrocarbon having a boiling point of no greater than 360°C by means of continuously supplying and hydrocracking a wax that is to be processed. The method is characterized by alternatingly providing: a period for hydrocracking the wax to be processed with the condition that the cracking rate defined by the belowmentioned formula (1) is X1 (%), satisfying the belowmentioned formula (2); and a period for hydrocracking with the condition that the cracking rate is X2 (%), satisfying the belowmentioned formula (3). Cracking rate (%) = [(amount of hydrocarbon having boiling point exceeding 360°C contained in 1g of wax to be processed) - (amount of hydrocarbon having boiling point exceeding 360°C contained in 1g of hydrocracking product)]×100/(amount of hydrocarbon having boiling point exceeding 360°C contained in 1g of wax to be processed) …(1); 30 ≤ X1 ≤ 90 …(2); and 0.1 ≤ X2/X1 ≤ 0.9 …(3).
