Abstract
An object of the present invention is to provide a porous hollow fiber membrane, which is capable of maximizing the inner surface area per volume of the porous hollow fiber membrane to reduce the amount of blood drawn out while maintaining safety in a blood purification application. The present invention provides a porous hollow fiber membrane containing a hydrophilic polymer, in which the outline of the inner surface in a cross section perpendicular to the longitudinal direction has an irregular shape, and IDi that represents the diameter (µm) of an inscribed circle for the outline of the inner surface, and IDo that represents the diameter (µm) of a circumscribed circle for the outline of the inner surface, each satisfy the following relationships: 95 ≤ IDi ≤ 1500; 100 ≤ IDo ≤ 1600; and 1.05 ≤ IDo/IDi ≤ 1.60.
