There is provided a method of producing a composite which is capable of suitably forming a silicone resin layer for preventing the facilitated transport film from entering the porous support in an acidic gas separation film formed by forming a facilitated transport film on a porous support, and the composite. The problem is solved by the method of producing a composite including hydrophilizing the surface of the porous support using a roll-to-roll system; and coating the hydrophilized surface of the porous support with a silicone coating solution that becomes the silicone resin layer using the roll-to-roll system.

In a spiral type acidic-gas separation module which is obtained by winding a laminate including an acidic gas separation layer that includes a facilitated transport film, a permeating gas channel member which includes a channel regulation member regulating an acidic gas channel that is a channel of an acidic gas having permeated through the facilitated transport film allows a difference in high-pressure deformation amount between a region where the channel regulation member is formed and a region other than the region to be set to 100 &#x3bc;m or less. In this manner, an acidic-gas separation module which prevents damage to the facilitated transport film and exhibits a predetermined performance for a long period of time is provided.
