PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module capable of completely removing suspended matters adhered to a hollow fiber membrane.SOLUTION: Raw water flows in an inflow port 1e, an inflow chamber 5, holes 4a, a treatment chamber 6, communication pipes 10, a discharge chamber 9, and an outlet 1f. Permeable water which has permeated hollow fiber membranes 2 is taken out from a permeable water chamber 7 via a take-out port 1g. When bubbling cleaning is performed, air is supplied from the inflow port 1e. The holes 4a and the communication pipes 10 are provided equally in whole area of potting parts 4, 3, therefore all upper parts of hollow fiber membranes 2, are sufficiently cleaned by bubbling cleaning. 【課題】中空糸膜に付着した濁質を万遍なく除去できる中空糸膜モジュールを提供する。【解決手段】原水は流入口１ｅ、流入室５、孔４ａ、処理室６、連通管１０、排出室９、及び排出口１ｆを流れる。中空糸膜２を透過した透過水は、透過水室７から取出口１ｇを介して取り出される。バブリング洗浄するときには、エアーを流入口１ｅから供給する。孔４ａ及び連通管１０がポッティング部４，３の全域に均等に設けられているので、すべての中空糸膜２の上部においても十分にバブリング洗浄される。【選択図】図１
