Abstract: An acidic gas separation module including: a perforated hollow central tube; and a layered body that is wound on the perforated hollow central tube and has, in the following order on a porous support: an acidic gas separation layer containing a water-absorbing polymer, a carrier, and water; and a flow channel material with a network structure having a thread intersection portion and an arithmetical surface roughness for a surface contacting the acidic gas separation layer in the thread intersection portion of 35 μm or less. The acidic gas separation module suppresses generation of flocculated water by maintaining the generation of turbulent flow in the flow channel material, effectively suppresses damage to the surface of the acidic gas separation layer by the flow channel material in the winding-on process during manufacture, and exhibits excellent acidic gas separation efficiency.
