  In addition, since the pickup unit 35 is made detachable with respect to the holder unit 31 that is attached and fixed to the film antenna, the parts including the window of the vehicle to which the film antenna is attached can be replaced, or the vehicle can be recycled. In some cases, the pickup unit 35 can be arbitrarily detached from the film antenna and then can be easily reattached.

  In addition, by standardizing the number of other contactors on the bottom of the holder 31 and the inner dimensions, the number of terminals of the pickup unit 35 attached to the holder 31 and the presence or absence of internal electronic circuits It is possible to deal with various types of pickup units 35 such as differences, and the holder unit 31 can be generalized so that the holder unit 31 can be used in common with a plurality of types of film antennas.

  In addition, since the holder portion 31 is attached in a state where the feeding terminal portion of the film antenna is covered with the other pieces 322 and 332 of the contactors 32 and 33 and the double-sided tape 34, the feeding terminal portion of the film antenna is removed even when the pickup portion 35 is removed. Can prevent foreign matter from adhering to the power supply terminal portion or corrosion from occurring without being exposed to the outside air.

  In particular, when the assembly process of the one film antenna is implemented in an automobile production line, the holder 31 is attached to the feeding terminal portion of the film antenna as early as possible, so that dust in the atmosphere can be obtained. This is effective in reliably preventing foreign matter from adhering to the power supply terminal portion due to, for example, and eliminating the occurrence of poor contact.

  In the second embodiment, unlike the first embodiment, the pickup unit 35 is not used as a housing structure including a case part and a cover part fitted to the case part. Although the terminal structure is simpler and simpler, it can be made to have a structure in which an electronic circuit such as a balun or LNA (low noise amplifier) is integrated with the substrate. It is possible as well.

  Moreover, although the said 1st and 2nd embodiment demonstrated both as what uses a coaxial cable, this invention is not restricted to this, As a cable which connects a film antenna and an external communication apparatus, Of course, it can also be applied to a single-wire cable, a coaxial cable having a plurality of central conductors arranged in parallel, or a bundle of single-wire cables bundled or arranged in parallel.
