PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module in which breakage of a hollow fiber membrane and a bundling tube due to expansion and contraction of the hollow fiber membrane caused by change of external environment such as temperature change can be effectively prevented.SOLUTION: In a hollow fiber membrane module in which a bundling tube is formed of a body section and head sections, that are located at both ends thereof, and O-rings for installing the bundling tube inside a housing are fitted on outer circumferential surfaces of the head sections, at least one of the head sections has a structure where the head section is divided into two while preserving a cylinder at a bundling tube end side and divided portions are able to slide while maintaining a connected state of the cylinder. |
