Abstract
PURPOSE:To be safe and sanitary having no environmental problem and to be advantageous in facilities and operation when an insulating coating material layer is formed on a copper conductor by forming an insulating coating material layer after the surface of a copper conductor is processed with phosphate formation. CONSTITUTION:When a insulating coating material layer is formed on a copper conductor, especially when epoxy resin is used as an insulating coating material layer, the insulating coating material layer shall be formed after a phosphate forming film is formed on the surface of the copper conductor. When the phosphate forming film is formed on the copper surface, if a process liquid of which phosphoric acid is a main constituent and an oxidant is contained is used a phosphate forming film can be formed securely and strongly on a copper surface. By the use of this method, advantages are expected in the phase of facilities and operation, and there is no problem in environmental conditions being safe and sanitary, and moreover the insulated copper conductor obtained is excellent in performance and quality.
