摘要
Provided is a separation membrane for processing an acidic gas-containing gas, which is provided with a uniform and dense separation layer that is free from defects. A separation membrane for processing an acidic gas-containing gas, which is provided with: an inorganic porous supporting body; an intermediate layer that is formed on the surface of the inorganic porous supporting body and contains a polysiloxane network structure or a hydrocarbon group-containing polysiloxane network structure; and a separation layer that is formed on the intermediate layer and contains a polyethylene glycol and a hydrocarbon group-containing polysiloxane network structure. The weight per square meter of the intermediate layer is 0.1-4.0 mg/cm2; and the weight per square meter of the separation layer is 0.1-3.0 mg/cm2.
