    Abstract: PROBLEM TO BE SOLVED: To provide a multilayer coating for an electric wire such as a telephone line cable and an electric wire for connection between electronic devices or in an electronic device. SOLUTION: In the multilayer coating for an electric wire made of a plurality of hardened light-hardening resin layers, a Young's modulus of a first layer is 5 to 100 MPa, and that of a second layer is 50 to 1,000 MPa. A wiring operation is easy, since a coated layer of an electric wire being excellent in its strength is simply and uniformly formed with irradiation of radioactive rays such as ultraviolet rays and a protective layer can be peeled off by a simple operation (a coating removal property), and there is no damage on a conductor itself at the time of the wiring operation.
