<p>A conductor (10) of the present invention has a conductive DLC film (1b) formed on a conductive base (2b). A conductive DLC film (1a) is formed on a conductive base (2a) and is supported by a conical spring electrode (3) to be in contact with the conductive DLC film (1b). Thus, a conductor is obtained which has good wear resistance and oxidation resistance and which is suitable for bringing conductive parts into contact.</p>
