摘要
The hollow fiber membrane bundle is used for an artificial lung, and is formed by integrating hollow fiber membranes 31 having hollow portions through which a fluid passes to form a cylindrical shape as a whole. Further, the hollow fiber membrane 31 is wound around the central axis O of the cylindrical body inclined with respect to the central axis O of the cylindrical body, and satisfies the following conditions. The hollow fiber membrane 31 has an inner diameter φd1 of 150 μm or less, the inclination angle θ of the hollow fiber membrane 31 with respect to the central axis O of the cylinder is 60 ° or less, the outer diameter φD1 of the cylinder, and the length of the cylinder The ratio φD1 / L with L is 0.4 or more.
