A mixed gas-separating membrane module having a high separating efficiency includes a cylindrical container having a mixed gas-feed section, a non-permeated gas-delivery section, and a middle section; a bundle of a plurality of hollow fibers each extending through the middle section and each having an end portion opening to the mixed gas-feed section and an opposite end portion opening to the non-permeated gas-delivery section; a pair of a first disk supporting the hollow fiber end portion opening to the mixed gas-feed section and partitioning the middle section from the mixed gas-feed section, and a second disk supporting the opposite hollow fiber end portions opening to the non-permeated gas-delivery section and partitioning the middle section from the non-permeated gas-delivery section, the first and second disks supporting the hollow fibers so that the hollow fibers are spaced from each other, to leave a continuous space between the hollow fibers; and a cylindrical film member surrounding the hollow fiber bundle to such an extent that the continuous space formed between the hollow fibers is connected to a permeated gas-delivery outlet of the middle section, the middle section, having a permeated gas-delivery outlet located close to the first disk and a carrier gas-feed inlet located close to or in the second disk, to allow the carrier gas fed into the middle section to flow through the continuous space, countercurrently to the flow of the mixed gas through the hollow fibers.

[What is claimed is:] [1.](1) a cylindrical container having a mixed gas-feed section having a mixed gas-feed inlet, a non-permeated gas-delivery section having a non-permeated gas-delivery outlet, and a middle section located between the mixed gas-feed section and the non-permeated gas-delivery sec

[What is claimed is:] [1.](1) a cylindrical container having a mixed gas-feed section having a mixed gas-feed inlet, a non-permeated gas-delivery section having a non-permeated gas-delivery outlet, and a middle section located between the mixed gas-feed section and the non-permeated gas-delivery section and having a carrier gas-feed inlet and a permeated gas-delivery outlet;(2) a bundle of a plurality of mixed gas-separating hollow fibers each comprising a shell portion and a hollow portion surrounded by the shell portion, each extending through the middle section of the cylindrical container and each having an end portion thereof opening to the mixed gas-feed section and an opposite end portion thereof opening to the non-permeated gas-delivery section;(3) a pair of a first hollow fiber-supporting disks, which support the end portions of the hollow fibers opening to the mixed gas-feed section and partitions the middle section from the mixed gas-feed section, and a second hollow fiber-supporting disk, which supports the opposite end portions of the hollow fibers opening to the non-permeated gas-delivery section and partitions the middle section from the non-permeated gas-delivery section,the first and second hollow fiber-supporting disks supporting the hollow fibers in such a manner that the hollow fibers are spaced from each other, to leave a continuous space between the hollow fibers; and(4) a cylindrical film member surrounding the hollow fiber bundle to such an extent that the continuous space formed between the hollow fibers is connected to the permeated gas-delivery outlet of the middle section,wherein, in the middle section, the permeated gas-delivery outlet is located close to the first hollow fiber-supporting disk and the carrier gas-feed inlet is located close to or in the second hollow fiber-supporting disk, to allow the carrier gas fed into the middle section through the carrier gas-feed inlet to flow through the continuous space formed between the hollow fibers and surrounded by the cylindrical film member, countercurrently to the flow of the mixed gas through the hollow portions of the hollow fibers.
