PROBLEM TO BE SOLVED: To provide a hollow fiber membrane which reduces various problems attributable to lowered strength of a hollow fiber membrane. SOLUTION: This hollow fiber membrane can solve the problem of a conventional hollow fiber membrane for hemocatharsis that enhancing the polymer fraction of a polymer solution can improve the pressure resistance and rupture strength of the hollow fiber membrane and can improve the assembly workability of a hemocatharsis device and can reduce blood leak troubles during clinical use, but on the other hand, sacrifices solute permeability. A hollow fiber membrane, which has the above advantage of the conventional hollow fiber membrane and, at the same time, can solve the problem of the conventional hollow fiber membrane, i.e. can simultaneously realize high strength and excellent solute permeability, can be stably manufactured on a commercial scale, without causing fiber defects and fiber breaking, by using liquid paraffin, from which low-boiling components have been removed, as a hollow forming agent for the hollow fiber membrane, and raising the nozzle temperature.
