The purpose of the present invention is to provide a hollow fiber membrane module by which cleaned platelets having a low total protein content and a high total platelet count can be prepared from a platelet suspension. Provided is a hollow fiber membrane module for separating foreign matters from a platelet suspension and thus cleaning platelets, said hollow fiber membrane module comprising: a housing which is provided with a platelet suspension inflow port, a cleaned platelet outflow port and a filtrate discharge port; and a hollow fiber membrane which is provided with holes not allowing the platelets to pass therethrough but allowing the foreign matters to pass therethrough, said hollow fiber membrane being positioned within the housing and filtering the platelet suspension, wherein, in the housing, the capacity of a space in the inflow side, which communicates with the platelet suspension inflow port and in which the platelet suspension before the filtration by the hollow fiber membrane is housed, is 30-400 mL and the water permeability of the module is 50-300 mL/Pa/hr. |
