Abstract
An electrically-conductive member having sufficient corrosion resistivity even when the electrically-conductive member is exposed to high potential environment and a method of manufacturing the electrically-conductive member are offered. An electrically-conductive member is obtained by a mist CVD method, by forming a metal oxide film on a base member of a separator, and the electrically-conductive member has an active potential range and a passive potential range in an anode polarization curve that is measured in a sulfuric acid aqueous solution having a sulfuric acid concentration that is 5.0×10−4 mol/dm3 at pH3 and having a temperature of 25° C., an anode current density that is 1×10−7 A/cm2 or less in the passive potential range, and the passive potential range reaching to an electric potential that is 1V.
