Abstract: In light of such conventional technical problems, it is an object of the present invention to provide a cell adsorption column which has an adsorbent with a surface area where there is less concern about denaturation and differentiation induction of cells caused by a contact of the adsorbent with the cells, and whose adsorbent-filled volume is small, and which has a compact property for improving operability and reducing a burden on a patient. The present invention provides a cell adsorption column filled with an adsorbent containing a fiber whose fiber diameter is 0.5 ?m or more and 10 ?m or less and having a surface area of 0.5 m2 or more and less than 10 m2, in which the adsorbent-filled volume is 100 mL or less.
