A method for producing a lubricant base oil, comprising: a first step of contacting a feedstock containing normal paraffins having not less than 20 carbon atoms with a first catalyst in the presence of molecular hydrogen to obtain a first produced oil, and a second step of contacting the first produced oil with a second catalyst in the presence of molecular hydrogen to obtain a second produced oil, wherein the first catalyst comprises a first carrier in which a fraction of an amount of NH 3 to be desorbed at 300 to 800°C based on a total amount of NH 3 to be desorbed is 80 to 90% in temperature-programmed desorption of NH 3 , a first metal that is at least one selected from metals that belong to Group VI in the periodic table and is carried on the first carrier, and a second metal that is at least one selected from metals that belong to Group VIII to Group X in the periodic table and is carried on the first carrier; a sum C 1 + C 2 of a proportion C 1 of the first metal contained in the first catalyst in terms of an oxide (% by mass) and a proportion C 2 of the second metal contained in the first catalyst in terms of an oxide (% by mass) is 22 to 36% by mass; and a ratio D 1 /D 2 between a content of the second metal D 2 (mol) and a content of the first metal D 1 (mol) in the first catalyst is 1.07 to 7.78. |
