A filter medium with which a leukocyte-containing fluid represented by whole blood can be treated to selectively remove the leukocytes therefrom and recover the erythrocytes, thrombocytes, and blood plasma by allowing these to pass through the medium. The leukocyte-removing filter is characterized by comprising a polymer having hydrophobic structural units and hydrophilic structural units and a porous substrate. The polymer is, for example, a copolymer of a hydrophobic monomer and a hydrophilic monomer or a hydrophilic polymer having hydrophobic structural units introduced therein by modification or chemical modification. |
