PURPOSE:To secure sealing of a feed liquid chamber from a filter chamber and to facilitate attachment and exchange of a filter to a pipeline by jointing a conical cap body having a small sized cylindrical part at the top to a bundle fixing part of hollow yarn bundles. CONSTITUTION:A conical cap body 4 is jointed to a bundle fixing part 5 of hollow yarn bundles housed in a cylindrical casing 1 having an opening at the top, and a seal member is attached to an annular groove 10 formed in a small sized part 9 at the top of the cap body 4 to support the bundle fixing part 5 with a flange 11. An opening communicating to an outlet 13 of filtrate and an inlet 14 of feed liquid is provided to the bottom wall of a cover body 2, and the small sized part 9 of the cap body 4 is inserted to the opening communicating to the outlet 13 of the filtrate sealing the clearance with an O-ring 15. The casing 1 and the cover body 2 are connected liquid tightly with a band coupling 17 interposing a gasket 18. The feed liquid is introduced through a feed liquid introducing pipe into a feed liquid chamber 19, and the component having permeated the hollow yarn is collected in a filter chamber 20, which is discharged after passing through the cap body from a filtrate discharge pipe.
