<p><P>PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module which can meet a demand for size reduction, can fully perform humidification and dehumidification, and is excellent in quality. <P>SOLUTION: A cylindrical bundle is formed from the second hollow fiber membrane 122 excellent in humidification efficiency and dehumidification efficiency. The first hollow fiber membrane 121 excellent in mechanical strengths is arranged so as to surround the periphery of the bundle. The first hollow fiber membrane is arranged near the first opening 111 and the second opening 112, and the first hollow fiber membrane buffers a shock of a fluid to reduce the shock which the fluid otherwise gives to the hollow fiber membrane in the bundle. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
