Abstract
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.
