摘要：
A manufacturing method for an acidic gas separation membrane sheet includes: a step of preparing a hydrophilic resin composition liquid for forming a hydrophilic resin composition layer (S1); a step of removing bubbles contained in the hydrophilic resin composition liquid (S2); a step of applying the hydrophilic resin composition liquid onto a first porous layer to form an applied layer on the first porous layer (S3); and a step of laminating a second porous layer on the applied layer to form a laminated body (S4). The step of removing bubbles (S2) includes: a step of applying a shear to the hydrophilic resin composition liquid (S2a); and a step of leaving the hydrophilic resin composition liquid (S2b).
