The present invention provides a process for production of a zeolite separation membrane with satisfactory separation performance. The process for production of a zeolite separation membrane according to the invention is comprising: a seed crystal-attaching step in which: a sealed body (10), which is obtained by sealing both ends of a cylindrical porous body (11) with sealing members (12a, 12b), is immersed from the sealing member (12a) end into a suspension (22) containing zeolite seed crystals; the suspension (22) is allowed to permeate from the exterior of the porous body (11) to the interior thereof; the zeolite seed crystals are thereby attached to the porous body (11); and a seed crystal-attached porous body is obtained; and a zeolite membrane-forming step in which: the seed crystal-attached porous body is contacted with a reaction solution containing the raw material of a zeolite membrane; the zeolite membrane is formed on the porous body (11); and a zeolite separation membrane is obtained.
