| Zusammenfassung: | The purpose of the present invention is to provide a porous hollow fiber membrane that has high strength while maintaining high purified water permeability. This porous hollow fiber membrane is formed from a fluororesin polymer, wherein there is a columnar structure oriented in the longitudinal direction of the porous hollow fiber membrane, and the molecular chain of the fluororesin polymer is oriented in the longitudinal direction of the porous hollow fiber membrane. |
