Abstract
A carbon dioxide separation membrane includes a skin layer having a function of separating carbon dioxide from a mixed gas, wherein the skin layer contains 30 to 90% by mass of a polymer resin in which a difference between an affinity to carbon dioxide and an affinity to at least one of hydrogen and helium, the affinities are expressed as free energy ΔG (kcal mol), is 4.5 kcal molor more and less than 10 kcal mol, and from 10 to 70% by mass of an organic liquid having an affinity to carbon dioxide.
