PROBLEM TO BE SOLVED: To provide a leukocyte removing filter, which is a device for selectively removing leukocyte from the blood without causing clogging at high yield in a short time, simple in structure as compared with a conventional device, and manufactured at a low price. SOLUTION: This leukocyte removing filter is formed by stacking two types of filters having different average fiber diameters D. The filter includes two types of filters: a pre-filter A having an average fiber diameter D ranging from 5.0μm to 10.0μm and a main filter B having an average fiber diameter D ranging from 1.2μm to 2.0μm. In the leukocyte removing filter, the respective filters A and B are stacked in this order to be directed from a blood introduction port to a lead-out port. COPYRIGHT: (C)2004,JPO&NCIPI
