Claim:
1. A method for producing lubricant base oil, wherein the method comprises: subjecting a catalyst to a coking treatment with a carbon containing compound, the coking treatment being at a temperature of 300° C. to 350° C. to obtain a hydroisomerization catalyst having a carbon content of 0.4% to 2.5% by mass, wherein the catalyst comprises a support having a one-dimensional porous structure including a 10-membered ring and at least one metal selected from the group consisting of group 8 to 10 metals of the periodic table, Mo, and W, supported on the catalyst; and contacting a hydrocarbon feedstock containing normal paraffins having 10 or more carbon atoms with the hydroisomerization catalyst in the presence of hydrogen at a hydroisomerization temperature of 370° C. to 450° C.
