【Task】 Provided is a hollow fiber membrane that can improve the removal and handling of harmful substances having a size typified by β2MG and the ease of module assembly in hemodialysis and hemodiafiltration. [Solution] The present invention is a hollow fiber membrane having an asymmetric structure having an inner diameter of 150 to 250 μm, a film thickness of 15 to 25 μm, a dense layer at least on the inner surface side, and a thickness of the dense layer of 0.01 to 2 μm. The hollow fiber membrane has a breaking elongation of 15% to 40% per single yarn. [Selection figure] None |
