<P>PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module in which a hollow fiber membrane is adhered to a cylindrical case inner circumferential surface by a resin, and the leakage failure due to the damage of the hollow fiber membrane in which the adhered zone is peeled off in a filter operation is surely prevented. <P>SOLUTION: The hollow fiber membrane module includes: a hollow fiber membrane bundle; a cylindrical case that stores the hollow fiber membrane bundle; and a resin part in which at least one side end of the hollow fiber membrane bundle is adhered/fixed to the cylindrical case. A groove is prepared at the inner circumferential surface of the cylindrical case in at least a portion of a part in which the resin part is prepared at about the longitudinal direction of the hollow fiber membrane module, an arc ring is prepared to fit in the groove and to be located between the cylindrical case and the hollow fiber membrane bundle, the arc ring has an overlap part at the circumferential direction, and the inner circumferential surface contacts to the outer periphery of the hollow fiber membrane bundle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
