Beschreibung
Zusammenfassung:	The present invention provides a porous carbon fiber which has an excellent permeation amount and excellent pressure resistance, which is prevented from the occurrence of detachment or cracking at an interface, and which can exhibit excellent properties needed for use as a support for a fluid separation membrane. The present invention is a porous carbon fiber having a bicontinuous porous structure, whereinthe average value Rave of the R value of the outer surface and the R value of the inside is 1.0 or more and 1.8 or less,the absolute value ΔR of the difference between the R value of the outer surface and the R value of the inside is 0.05 or less, andR value is a carbonization progression degree calculated from a Raman spectrum in accordance with the following formula:R value=(intensity of scattering spectrum at 1360 cm−1)/(intensity of scattering spectrum at 1600 cm−1).
