Complex for acid gas separation, module for acid gas separation, and method for manufacturing module for acid gas separation

[Problem] The purpose of the invention is to provide a complex for acid gas separation that can suppress gas leaks and that has high separation performance and durability. [Solution] A complex (1) for acid gas separation is provided with an acid gas separation film (2) comprising a porous support (2B) with an average pore diameter of 0.5 [mu]m or less and an acid gas separation layer (2A) that is disposed on top of the porous support (2B) and includes a water-absorbent polymer and an acid gas carrier that reacts with acid gas in a source gas, and also is provided with a gas-permeable flow path member (5) through which acid gas that has reacted with the acid gas carrier and passed through the acid gas separation layer (2) flows. The complex has a seal section (3) in which a region on the periphery of the gas-permeable flow path member (5) and the porous support (2B) that needs to be sealed is sealed with a resin. The resin is an epoxy-based resin, the Tg of the epoxy-based resin is at least 90 DEG C, and inorganic filler content is 30% or less by mass.
