PROBLEM TO BE SOLVED: To accurately lead out a feeder conductor or short-circuiting conductor from the prescribed feed position or short-circuiting position of a radiating conductor, to secure a resonance frequency or impedance, and to prevent the resonance frequency or impedance from deviating or to prevent the signal feeding from being disabled by impacts from the outside. SOLUTION: A radiating conductor 2 in which a feeder conductor 22 and a short-circuiting conductor 23 are integrally formed, is attached to a guide member 3 mounted on a circuit board 1. The radiating conductor, the feeder conductor and the short-circuiting conductor are integrated, so that the feeder conductor and the short-circuiting conductor can be accurately led out from the prescribed feed position and short-circuiting position of the radiation conductor, and dispersion of the characteristics of an antenna is reduced as well. Since a spring 33 is provided for pushing the top ends 22A and 23A of the feed conductor and the short-circuiting conductor into a feed pattern and a short-circuiting pattern on the circuit board, the top ends of the feed conductor and the short-circuiting conductor are not detached from the feed pattern and the short-circuiting pattern on the circuit board even when an impact is applied to.
