Abstract

The present invention provides a hollow fiber membrane module that can minimize the decrease of the membrane filling rate caused by arrangement of diffuser pipes, and sufficiently carry out air bubbling. The hollow fiber membrane module includes a hollow fiber membrane bundle made up with a plurality of hollow fiber membranes, an upper potting section and a lower potting section in which ends of the hollow fiber membrane bundle are put together by the use of a resin in such a way that the hollow fiber membranes maintain opening at ends, and a diffuser pipe arranged on an upper surface of the lower potting section. A cross-sectional shape of the diffuser pipe is a longer shape in a vertical direction than in a horizontal direction. A cross-sectional area of the diffuser pipe continuously and step-by-step becomes narrow toward a terminal end from an air inlet side that supplies air to the diffuser pipe.
