The method for producing an MTW-type zeolite according to the present invention includes: mixing a silica source, an alumina source, an alkali source, a lithium source, and water so as to obtain a reaction mixture having a composition represented by specific molar ratios; (2) adding an MTW-type zeolite which has a SiO2/Al2O3 ratio of 10 to 500 and does not contain an organic compound, as a seed crystal, to the reaction mixture in a proportion of 0.1 to 20% by weight relative to the silica component in the reaction mixture; and (3) airtightly heating the reaction mixture, to which the seed crystal has been added, at 100 to 200° C.
