The ends of the hollow fibers inserted into the case are made to protrude from the edge of the case, and the ends of the case and the hollow fibers are dipped in a binder and bonded to the spaces between the inner wall of the case and the hollow fibers and between each hollow fiber. By including the step of filling the case with the agent and the step of cutting off the end of the hollow fiber that protrudes from the edge of the case, the work is easy, the end opening of the hollow fiber is not blocked, and the case is removed. There is no unnecessarily crowded space between the hollow fibers in the chamber (the filled binder does not reduce the effective area of the hollow fibers, and furthermore, the hollow fibers are not held or in an unstable state due to insufficient filling of the binder). A hollow fiber module was obtained.
