Abstract

A flexible blood filter allowing smooth flow of a fluid and being excellent in peelability, pressure-resistance and centrifugal resistance. The blood processing filter, which consists of a first filter member for eliminated coagulated matters from blood and a second filter member for eliminating leucocytes provided in the downstream of the first filter member, is characterized in that the fluid permeability ranges from 3 to 40 cc/cm2/sec per cm of the thickness between the second filter member and a container located in the outlet side.
