Abstract
Disclosed is a fluid treating apparatus of hollow fiber type. The apparatus can prevent channeling or stagnation of the fluid which flows inside it by specifying the densities of the hollow fibers and the warps forming a hollow fiber sheet and the laminating conditions for laminating the hollow fiber sheets to form a laminate which is to be housed in a housing.
