摘要： Disclosed is a gas separation composite membrane comprising a polyamidoamine dendrimer (A) having a specific group, a vinyl alcohol-based polymer (B) containing 0.5 to 5 mol% of carboxyl groups, and a crosslinking agent (C) having an azetidinium group, wherein the mass ratio (A)/(C) of the polyamidoamine dendrimer (A) to the crosslinking agent (C) having an azetidinium group is 20/80 to 65/35, and the mass ratio (B)/(C) of the vinyl alcohol-based polymer (B) to the crosslinking agent (C) having an azetidinium group is 20/80 to 80/20. Thus, a gas separation composite membrane capable of separating a specific type of gas from a mixed gas containing water vapor is provided.
