PROBLEM TO BE SOLVED: To reduce production cost of a hollow fiber membrane module and improve productivity of the same, and improve sealability of a seal part.SOLUTION: A hollow fiber membrane module comprises: a cylindrical case 1 on which a plurality of flow passage holes 1a, 1b is opened; a plurality of hollow fiber membranes 2 formed into a bundle shape and filled in the case 1; and potting parts 3, 4 for sealing both end opening parts of the case 1 so that only both ends of internal pores of the hollow fiber membrane 2 open in both end opening parts of the case 1. On an outer peripheral face of the case 1, annular holders 5, 6 having grooves 5a, 6a respectively for fitting seal rings are integrally joined in a contact state. |
