PURPOSE:To obtain a module which has strength and is easy to tightly seal an air-permeation membrane by making a discharge port of fluid which has an inner shape less in the change of crosssectional area rectangular to the direction of an air stream such a structure that the cut part of a reinforced plate is held from both sides. CONSTITUTION:When decompressing and sucking the inside of a vacuum tube 7 with a vacuum pump, the inside of a discharge port 4 for fluid which is connected to the vacuum tube 7 is made to a decompressed state and pressure difference is caused in an air-permeable membrane 1 via a permeable substance 3. When a space part is formed between a reinforced plate 2 and the membrane 1, the membrane 1 is held and reinforced by the reinforced plate 2. The outer face of a connection part 4a of the discharge port 4 is made smooth in the surface so that it is sealed easily and tightly with a double-face adhesive tape 6, and made to the thickness wherein two sheets of the substance 3 and the reinforced plate 2 are allowed to coincide. A difference in level is removed by thinning slowly the both end faces rectangular to the direction of oxygen- enriched air stream and the tight seal of the membrane 1 is made easy by means of the tape 6.
