There is provided a high-quality spiral-type acidic gas separation module which is obtained by winding a laminate including an acidic gas separation layer that has a facilitated transport film and which has no defects in the facilitated transport film, in which the average value of the fiber diameter of a supply gas channel member is in a range of 100 μm to 900 μm, and the area ratio of concave portions inscribed in a hemisphere having a diameter greater than or equal to three-quarters of the fiber diameter of the supply gas channel member is 50% or less with respect to a surface of an auxiliary support film of a porous support that is on the side opposite to the facilitated transport film. |
