摘要： Provided is a separation membrane manufacturing method capable of easily manufacturing a dense separation membrane. The separation membrane manufacturing method comprises a membrane forming step of forming a separation membrane precursor containing a separation membrane precursor solution on the surface of cells formed in a porous monolith substrate; and a drying step of performing ventilation drying by passing hot air through the cells having the separation membrane precursor in the monolith substrate to dry the separation membrane precursor. During the ventilation drying in the drying step, the temperature of the monolith substrate having the separation membrane precursor is raised to 90° C. within 15 minutes from the start of the passing of the hot air at such a rate of temperature rise that an average rate of temperature rise is 7° C./min or more from the start of the passing of the hot air until the temperature reaches 90° C.
