Disclosed is a method for producing a DDR zeolite, which can be carried out using materials that are less harmful to the environment. The method for producing a DDR zeolite has a short hydrothermal synthesis time and does not require constant stirring of the starting material solution. Specifically disclosed is a method for producing a DDR zeolite, which comprises: a starting material solution preparation step in which a starting material solution that contains 1-adamantaneamine, silica (SiO2) and water at a molar ratio 1-adamantaneamine/SiO2 of 0.002-0.5 and a molar ratio water/SiO2 of 10-500 but does not contain ethylenediamine is prepared; and a crystal growth step in which hydrothermal synthesis is carried out while having the raw material solution and a DDR zeolite powder in contact with each other, so that crystals of DDR zeolite are grown using the DDR zeolite powder as a seed crystal.
