Abstract
Disclosed herein are methods of measuring, adjusting and uniformalizing a sectional area ratio of a metal-covered electric wire, a method of cleaning an electric wire, a method of manufacturing a metal-covered electric wire, an apparatus for measuring a sectional area ratio of a metal-covered electric wire, and an apparatus for electropolishing a metal-covered electric wire. Electric resistance values of first and second materials are previously stored respectively so that a sectional area ratio of a metal-covered electric wire is calculated on the basis of the as-stored values and an actually measured electric resistance value of the metal-covered electric wire. Measurement and uniformalization of a sectional area ratio of a metal-covered electric wire and cleaning of an electric wire are carried out by dissolving surface layer parts of the electric wires by electropolishing.
