Abstract
An electrical conductive member includes: an electrical conductive structure including: a substrate; an electrical conductive carbon layer provided on at least one surface of the substrate and containing electrical conductive carbon; and a middle layer 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 between 1.4 and 1.9.
