PROBLEM TO BE SOLVED: To provide a blood component adsorption column capable of adsorbing and eliminating inflammatory cytokines and leukocytes highly efficiently and achieving extracorporeal circulation while suppressing pressure rise.SOLUTION: A blood component adsorption column includes a container having a blood inlet 1 and blood outlet 1 and a blood component adsorption material 2 with which the container is filled. The blood component adsorption material is formed of a texture or kitted fabric. An opening rate of the texture or knitted fabric is 3% or more and less than 10%. A filling density of the blood component adsorption material is 0.30 g/cmor more and 1.30 g/cmor less. A value obtained by multiplying the opening rate and filling density is 1.1% g/cmor more and less than 3.9% g/cm.SELECTED DRAWING: Figure 1【課題】炎症性サイトカイン及び白血球を高効率に吸着除去することが可能であり、かつ、圧力上昇を抑制しつつ体外循環ができる、血液成分吸着カラムを提供する。【解決手段】血液導入口1及び血液排出口1を有する容器と、容器内に充填される血液成分吸着材料2とを備え、血液成分吸着材料は、織物又は編地からなり、上記織物又は上記編地の開口率は、3%以上10%未満であり、血液成分吸着材料の充填密度は、0.30g/cm3以上1.30g/cm3以下であり、開口率と充填密度を乗じた値は、1.1%・g/cm3以上3.9%・g/cm3未満である血液成分吸着カラムを提供する。【選択図】図1
