Summary:To provide a cartridge type hollow fiber membrane module which is capable of preventing leakage and germ contamination by a crack into a potting agent even when steam sterilization to be used for food and pharmaceutical purposes is applied.SOLUTION: In a housing and a cartridge type hollow fiber membrane module having a cartridge, the cartridge is provided with: a plurality of hollow fiber membranes; and first and second potting parts. The housing has inside a flange support part A supporting the cartridge and an inclined support part B. The cartridge has a flange part A' contacting the flange support part A and an inclined part B' contacting the inclined support part B reversibly by a change of temperature in the cartridge type hollow fiber membrane module, a clearance occurs at 25°C between the support part B and a radial direction of the inclined part B', and the inclined support part B' and the support part B contact each other at 80°C.SELECTED DRAWING: Figure 1 【課題】食品、医薬品用途に使用される蒸気滅菌を適用してもポッティング剤へのクラックによるリークおよび雑菌汚染を防止できるカートリッジ式中空糸膜モジュールを提供すること。【解決手段】ハウジングと、カートリッジを有するカートリッジ式中空糸膜モジュールにおいて、カートリッジが、複数の中空糸膜と、第1および第2ポッティング部とを備え、ハウジングはその内部に、カートリッジを支持するつば支持部Aおよび傾斜支持部Bを有し、カートリッジは、つば支持部Aと当接するつば部A'と、カートリッジ式中空糸膜モジュール内の温度変化によって可逆的に傾斜支持部Bと当接する傾斜部B'を有し、25℃では支持部Bと傾斜部B'の径方向の間にクリアランスが生じ、温度80℃で傾斜支持部B'と記支持部Bとが当接する。【選択図】図1
