An object of the present invention is to improve the drawbacks of the prior art, to suppress the occurrence of airlock, to reduce the amount of eluate, and to hardly generate residual blood, and a semi-dry type hollow fiber membrane module and hollow fiber membrane It is to provide a method for manufacturing a module. A hollow fiber membrane is built in a module case, a filling step of filling a liquid into a first liquid passing space which is an inner surface of the hollow fiber membrane, a blow step of extracting the liquid using a gas, and then an inert gas. In the manufacturing method of the hollow fiber membrane module which has the process of irradiating with radiation | emission after encapsulating, The manufacturing method of the hollow fiber membrane module characterized by satisfy | filling the following requirements. 1) A copolymer polymer composed of a hydrophilic unit and a hydrophobic unit exists on at least the inner surface side of the hollow fiber membrane. 2) The liquid retention is 10 to 350% by weight. 3) The direction of blowing the gas and the direction of sealing the inert gas are the same.
