ON-VEHICLE ANTENNA

PROBLEM TO BE SOLVED: To reduce the number of components of an on-vehicle antenna.SOLUTION: An antenna element 22 is printed on a spoiler 10 with a conductive paint. The conductive paint includes a thermosetting binder. The binder cures at a temperature lower than a melting point of an insulator which forms the spoiler 10. In the step of printing the antenna element 22 on the spoiler 10, after applying the conductive paint to the spoiler 10, the conductive paint is cured by heat so that the conductive paint is fixed to the spoiler 10. The conductive paint may include an ultraviolet curable binder. In this case, after applying the conductive paint to the spoiler 10, the conductive paint is irradiated with ultraviolet rays. Thus, the conductive paint is cured and fixed to the spoiler 10.
