PROBLEM TO BE SOLVED: To provide a simple and inexpensive injection vessel used for injecting a sealant of module ends in a manufacturing process of a hollow fiber membrane module by a centrifugal potting method, reduced in clogging frequency, uniformizing distribution amount of the distributed potting material, and reduced in the occurrence rate of defective articles, and a manufacturing method of the hollow fiber membrane module using it. SOLUTION: The potting material injection vessel has a central distributor with a bottom and facing sidewalls raised from the bottom, and injection nozzles separated from the central distributor. The injection nozzles are attached to ends of the facing sidewalls opposite to a central axis of the central distributor, and has storage parts of the potting material. The storage part has a shape tapered toward the downstream side from the upstream side. The potting material is centrifugally injected by using the potting material injection vessel tiltedly formed in relation to the central axis of the central distributor. COPYRIGHT: (C)2009,JPO&INPIT
