A ceramic sol whose average pore diameter after the sol itself has been formed into a membrane is larger than that of a ceramic separation membrane and is 10 nm or less is brought into contact with the surface of a ceramic separation membrane having an average pore diameter of 0.5 to 10 nm, and the ceramic separation membrane having the ceramic sol is dried and then fired to repair a defect portion of the ceramic separation membrane.</p> |
