Abstract
The present invention provides a carbon membrane for fluid separation that can suppress the breakage of a carbon membrane installed in a separation module during a vacuum desorption step before permeation of a fluid or during permeation of a fluid. The present invention provides a carbon membrane for fluid separation including a porous carbon support and a dense carbon layer provided on the porous carbon support, wherein the porous carbon support has an Rs value of 1.0 or less, where the Rs value is an R value (peak intensity of D-band (1360 cm−1)/peak intensity of G-band (1580 cm−1)) calculated from a Raman spectrum.
