This method for producing a lubricant base oil is provided with a step for putting a base-stock oil, obtained by mixing a heavy hydrocarbon oil containing normal paraffin and having a boiling point of 470°C or higher with a light hydrocarbon oil containing normal paraffin and having a boiling point of 330°C or higher and less than 470°C, in contact with a hydrogenation/isomerization catalyst while in the presence of hydrogen. |
