A plurality of hollow fibrous membranes 1 are stored in the outer cylinder 4 in a state in which they are bundled in parallel around a permeate collection tube 3 having , the permeated liquid collecting pipe 3 and the outer cylinder 4 are fixed to each other with casting resin 5. The inner surface 51 of the casting resin 5 at the upper end is the end of the permeate collection pipe 3, that is, the opening surface 2 of the hole 2 located at the top in FIG.
It is substantially flush with the opening surface 21 in the vicinity of the opening surface 21, and is curved in a concave shape toward the outside of the outer cylinder 4 from the opening surface 21. That is, the casting resin inner surface 51 is formed such that the thickness of the casting resin 5 gradually increases as it approaches the inner wall of the outer cylinder 4 from the central axis P of the permeated liquid collection tube 3. Here, the degree of curvature is not particularly limited, and the difference between the casting resin thickness l 1 near the outer wall of the permeate collection pipe 3 and the casting resin thickness l 2 near the inner wall of the outer cylinder 4 is l If 2 ~ l 1 is even small,
The effects of the present invention can be obtained, and l2 to l1 is usually about 5 to 50 mm, although it varies depending on the length and diameter of the outer cylinder 4. Further, a joint 8 having a liquid supply nozzle 6 and a permeated liquid extraction nozzle 7 is provided at one end of the outer cylinder 4, and a joint 10 having a concentrated liquid extraction nozzle 9 is provided at the other end.
