PURPOSE:To obtain a practically sufficient reception performance without a projecting antenna part at the outside of a vehicle by arranging a plate metallic body to an outer side lower face of a car body with a gap by an insulator and connecting a feeder end to the metallic body and the car body respectively. CONSTITUTION:An antenna 11 is provided with a metallic plate 11 being an antenna element. The surface of the metallic plate 11a is coated by an insulator 11b made of a reinforced plastic such as FRP and arranged to a face of the lower part 13 of a rear trunk with a prescribed gap. That is, the car body 12 and the metallic plate 11a are insulated electrically and a core wire is connected to the metallic plate 11a, the outer conductor of one end of the feeder 14 such as a coaxial cable is connected to the car body 12 and the other end is connected to a receiver. Thus, since the the metallic plate 11a being the antenna element is arranged to the outer side face of the car body 12, the external appearance of the car body is not deteriorated and no wind break noise is caused and noise from a microcomputer in the car body and a heater or the like is shielded.
