PROBLEM TO BE SOLVED: To provide a magnetic wire, composed of a metal with a shield effect like proper iron, and a conductor with a conductive property like proper copper, expected to have further shielding effect, and easy to obtain a property at high frequency area. SOLUTION: The magnetic wire 5 uses an annealed copper as a conductor 1, and a polyurethane film 2 is formed on the outer periphery of the conductor by coating and burning a polyurethane paint, and a polyurethane magnetic film 3 is formed on the outer periphery of the above by coating and burning a polyurethane magnetic paint in which, iron powder is mixed, and a polyurethane film 4 is formed on the outer periphery of the above.
