  • Publication number: 20110287336
    Abstract: An electrical conductive member includes: an electrical conductive structure including: a substrate (31, 152, 252, 352, 452); an electrical conductive carbon layer (33, 155, 254, 354, 454) provided on at least one surface of the substrate and containing electrical conductive carbon; and a middle layer (32, 154, 256, 356, 456) interposed between the substrate and the electrical conductive carbon layer. An intensity ratio R (ID/IG) of a D-band peak intensity (ID) to a G-band peak intensity (IG) measured by a Raman scattering spectroscopic analysis in the electrical conductive carbon layer is 1.3 or more.
