PURPOSE: Provided is an inexpensive hollow-fiber membrane module capable of preventing potting layers from peeling or coming off from a cylindrical casing when potting ends are cut off. CONSTITUTION: The hollow-fiber membrane module comprises a cylindrical casing(3) having an inner wall, an inlet port(1) at one end portion and an outlet port(2) at the other end portion, a hollow-fiber membrane bundle(4) contained in the cylindrical casing, potting layers(5,6) for fixing the hollow-fiber membrane bundle to the inner wall at both end portions of the hollow-fiber membrane bundle, a header(10) having an outlet port(9) for liquid to be treated being provided to one of the cylinder end portions, a header(8) having an inlet port(7) for the liquid to be treated being provided to the other cylinder end portion, and baffle cylinders having slits extending in a direction at an angle to an axis extending along the cylindrical casing fitted in the potting layers.
