To produce a composite for acid gas separation, the composite having excellent separation characteristics, with high productivity. A solution is a method of producing a composite (52) for acid gas separation, the composite provided with an acid gas separation facilitated transport membrane having a function of separating an acid gas in a raw material gas on a porous support (12), according to a roll-to-roll process, including: a preparation step for preparing a coating liquid for formation of an acid gas separation facilitated transport membrane, the coating liquid containing a hydrophilic compound, an acid gas carrier and water; a coating step for coating onto the support the coating liquid for formation at a liquid membrane thickness of 0.3 mm to 3.0 mm; a winding step for drying the coated liquid membrane in a drying oven (40) to form the acid gas facilitated transport membrane, and winding around a winding roll (50) the composite (52) for acid gas separation formed through formation of the acid gas facilitated transport membrane on the support (12), wherein humidity in a winding step unit (5) in which the winding step is performed is measured to control the humidity to be 10% or more and 60% or less, and the winding step is performed under the controlled humidity conditions. |
