Provided is a method for producing a ceramic separation membrane which has a good balance between water impermeability and gas permeability at a high level. This method for producing a ceramic separation membrane comprises: formation of a ceramic porous membrane on the surface of a porous base; application of at least a fluorine atom-containing organosilicon compound over the porous membrane; and a heat treatment of the porous membrane, to which the organosilicon compound has been applied, at a temperature that is not less than the boiling point of the organosilicon compound. Consequently, fluorine atoms derived from the organosilicon compound are left at least on the surface of the porous membrane. |
