To provide a multitubular separation membrane module capable of making the diameter of an end plate small.SOLUTION: A multitubular separation membrane module comprises: a cylindrical housing 2; a plurality of tubular separation membranes 3 disposed in the longitudinal direction of the housing 2; a support plate 5 supporting the tubular separation membranes 3; and baffles 7, 8 being disposed in parallel with the support plate 5 and having insertion holes 7a, 8a inserted with the tubular separation membranes. An inflow chamber 12 is formed between the support plate 5 and the baffle 8. A flowing-in chamber 20 is disposed so as to surround the inflow chamber 12. A fluid to be treated flowing-in from an inflow port 9 flows from each opening 21 into the inflow chamber 12 after being flown in the flowing-in chamber 20 in a circumferential direction. A bottom cover is connected to an inward flange at the lower end of the housing 2.SELECTED DRAWING: Figure 1 【課題】エンドプレートの直径を小さくすることができる多管式分離膜モジュールを提供する。【解決手段】筒状のハウジング２と、ハウジング２の長手方向に配置された複数の管状分離膜３と、管状分離膜３を支持する支持板５と、該支持板５と平行に配置され、管状分離膜が挿通された挿通孔７ａ，８ａを有するバッフル７，８とを有する。支持板５とバッフル８との間に流入室１２が形成されている。流入室１２を取り巻くように流入チャンバ２０が設けられ、流入口９から流入した被処理流体が流入チャンバ２０内を周方向に流れた後、各開口２１から流入室１２に流入する。ハウジング２の下端の内向きフランジにボトムカバーが連結されている。【選択図】図１
