Hollow fiber membrane and method for producing hollow fiber membrane
A hollow fiber membrane that is a hollow fiber type semipermeable membrane, wherein a Raman value is 70% or more, and the Raman value is a ratio of a minimum value to a maximum value of peak intensities, which are intensities of maximum peaks in each of multiple Raman spectra obtained by Raman spect...

| Zusammenfassung: | A hollow fiber membrane that is a hollow fiber type semipermeable membrane, wherein a Raman value is 70% or more, and the Raman value is a ratio of a minimum value to a maximum value of peak intensities, which are intensities of maximum peaks in each of multiple Raman spectra obtained by Raman spectroscopy at multiple points in a membrane thickness direction of a transverse cross-section of the hollow fiber membrane in a state of being swollen with water. |
