PURPOSE:To shorten the overall length of an antenna fitted to a running vehicle such as a car by covering a conductive core such as a copper wire with an electric insulating film, and sticking a carbon film or carbon coating film to said insulating film. CONSTITUTION:A copper wire 1 is covered with an electric insulating film 2 of a synthetic resin material and to this film 2, a carbon film 3 formed by impregnating carbon fiber with a thermosetting synthetic resin material and then setting the resin. Then, a fitting metallic fixture 7 is fitted to form an antenna for a running vehicle. In this constitution, the conductive core and carbon film perform transmission and reception additionally to improve transmitting performance and receiving performance, and also to shorten the overall length of the antenna, which is durable mechanically. |
