A white blood cell-removing device has a bag-shaped housing made of soft resin, a white blood cell-removing filter member partitioning the inside of the housing into an inlet side blood chamber and an outlet side blood chamber, a blood inlet port positioned at one side of the housing and communicating with the inlet side blood chamber; and a blood outlet port positioned at the other side of the housing and communicating with the outlet side blood chamber. An inner surface (the outlet side blood chamber) of the bag-shaped housing is a unevenness surface. The white blood cell-removing filter member has a filtering part and a non-filtering part formed on the entire periphery of the filtering part.

[ What is claimed is:] [18.]18. A white blood cell-removing method which is carried out by using a white blood cell-removing device having: a bag-shaped housing made of soft resin; a white blood cell-removing member partitioning an inside of said housing into an inlet side blood chamber and an outlet side blood chamber; a blood inlet port positioned at one side of said housing and communicating with said inlet side blood chamber; and a blood outlet port positioned at the other side of said housing and communicating with said outlet side blood chamber,said white blood cell-removing method being carried out in a state where an unprocessed blood filling container containing unprocessed blood is connected with said white blood cell-removing device at a blood flow inlet side thereof through a first tube, and a processed-blood collection container made of soft resin and collecting treated blood is connected with said white blood cell-removing device at a blood flow outlet side thereof through a second tube,said method comprising the steps of:introducing blood into said white blood cell-removing device from said unprocessed blood filling container;feeding air inside said white blood cell-removing device to said processed blood collection container;feeding said blood contained in said unprocessed blood filling container to said processed blood collection container by passing said blood through said white blood cell-removing device; andfeeding air in said processed blood collection container to said outlet side blood chamber of said white blood cell-removing device and/or to said second tube by pressing said processed blood collection container; andcollecting processed blood from said outlet side blood chamber of said white blood cell-removing device and/or processed blood from said second tube in said processed blood collection container.
