Abstract
A filter element includes a bundle of hollow fibers made of first polyolefin. The bundle has at least one end sealed with second polyolefin having an average molecular weight in the range of 1,000 to 16,000. The filter element is produced by a method including the steps of fusing the second polyolefin having a fusion point lower than that of the first polyolefin, attaching the fused second polyolefin to at least one end of the bundle, allowing the attached second polyolefin to set, thereby providing the bundle with a sealed portion, and cutting off the leading end of the sealed portion.
