PURPOSE:To support bundles of hollow yarns bundled in U-shape in a hollow yarn filtration module while keeping enough distance among respective hollow yarns in the whole length to allow a liquid flow and cleaning air to flow well among respective hollow yarns and to prevent suspended substances from adhering to the hollow yarns and the hollow yarns from sticking each other and becoming like a rod. CONSTITUTION:Supporting members 8, 9 having a first supporting point and a second supporting point apart from a first supporting point are installed in the U-shaped end part 10 of a hollow yarn bundle and the hollow yarns 2 are hooked on them to form wide U-shape parts of respective hollow yarns and at the same time while supporting respective hollow yarns dispersely, one- side ends of U-shape hollow yarns 2 and the other-side ends of the U-shape hollow yarns are made to have spaces among them by installing spacers 12, 13 near a fixing part 3 and thus a hollow yarn filtration module is composed.
