PROBLEM TO BE SOLVED: To provide a filter device by which blood is transported into a fiber from an inlet with a low load, and the fibers are uniformly put in. SOLUTION: Masses are exchanged between the two mediums separated by a membrane in this filter device, the membrane has the shape of a hollow- fiber bundle, the cavity of the bundle forms a first flow space, at least one inlet or outlet chamber 10 connected to the first flow space, supplying the medium to the bundle and removing the medium from the bundle is formed, the chamber is connected to the inlet or outlet 20 and disposed adjacent to a substantially circular or semicircular channel 12 opened toward the end of the hollow fiber, and the channel is disposed almost in the center of the bundle and has a cross-sectional area decreasing in the flow direction and an outer diameter smaller than the diameter of the bundle. |
