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 3 containing a separation membrane precursor solution on the surface of cells formed in a porous monolith substrate 1; and a drying step of performing ventilation drying by passing hot air 15 through the cells 2 having the separation membrane precursor 3 in the monolith substrate 1 to dry the separation membrane precursor 3. During the ventilation drying in the drying step, the temperature of the monolith substrate 1 having the separation membrane precursor 3 is raised to 90°C within 15 minutes from the start of the passing of the hot air 15 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.

The organic-inorganic composite of the present invention includes an organic compound having a carbonyl group, an inorganic compound containing a metal component, and a silver component. The ratio of the number of metal atoms in the inorganic compound to the number of carbon atoms in the organic compound is from 0.04 to 1.60, and the ratio of the number of silver atoms in the silver component to the number of carbon atoms in the organic compound is from 0.07 to 0.55. The organic-inorganic composite may include, for example, an inorganic compound having a metal matrix structure containing a metal M and oxygen, an organic compound having a carbonyl group, and silver ions. The carbonyl group is bonded to a side chain R 1 of the organic compound and has an end group R 2 .
