PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module capable of being manufactured easily at a small number of manufacturing steps. SOLUTION: Since a hollow fiber membrane bundle 3 is covered with a nonwoven fabric 4 and the fabric-covered bundle 3 can be packed in a module case 2 easily, such conventional problems are solved that several man hour is necessary for winding a hollow fiber membrane, the work of packing the wound membrane is very difficult and the membrane is apt to be damaged during the work of inserting the wound membrane into the case 2. Therefore, this module can be manufactured easily by a small number of manufacturing steps. |
