This method for producing a lubricant base oil includes: a separation step for supplying a hydrocarbon oil to one side of a separation membrane that includes a zeolite membrane and recovering, from the other side of the separation membrane, a permeate that has permeated through the separation membrane; and a base oil production step for obtaining a lubricant base oil from a stock oil including the permeate. The hydrocarbon oil has a 10 vol% distillation temperature of 320ºC or higher and a 90 vol% distillation temperature of 500ºC or lower. The content of normal paraffins in the permeate is greater than the content of normal paraffins in the hydrocarbon oil.
