[0001] Provided is a simple method for regenerating a zeolite membrane which has been exposed to water. The method for regenerating a zeolite membrane is a method for regenerating a zeolite membrane which is formed on a ceramic porous body and subjected to removal treatment of structure directing agent. Heating is performed at a regeneration temperature at which the difference in ratio of thermal expansion amount between the ceramic porous body and the zeolite membrane is 0.3% or less when 40°C is set as datum. The regeneration temperature is preferably a temperature not exceeding the oxidative pyrolysis temperature of the structure directing agent used in the formation of the zeolite membrane.
