PROBLEM TO BE SOLVED: To provide a method for producing zeolite membranes by which homogeneous zeolite membranes each having a sufficient permeation flux can be efficiently produced, and the permeation flux can sufficiently be prevented from fluctuating even when a plurality of zeolite membranes are produced. SOLUTION: The method for producing the zeolite membrane includes: a membrane element forming process for forming a zeolite membrane element on the surface of a support by bringing a reaction solution containing a raw material of the zeolite membrane into contact with the support; a separation process for separating the zeolite membrane element from the reaction solution; and a cleaning process for obtaining the zeolite membrane by supplying cleaning water 12 to a contact place between the zeolite membrane element 1 and brush hairs 15a while rotating at least one rotary brush 15 having a brush support 15b and the brush hairs 15a provided on the surface of the brush support 15b and bringing the brush hairs 15 into contact with the zeolite membrane element 1, and at the same time, washing the zeolite membrane element 1 by continuously changing the contact place between the rotary brush 15 and the zeolite membrane element 1.
