  • the film antenna device 1 can be attached to the window glass 80 easily since the film antenna units 10A and 10B and the circuit board unit 30 can be formed in an integrated type and there is no need for careful attachment of a power feeding part of the film antenna units 10A and 10B.
  • the film antenna supporting unit 25b of the bottom case 20b is bonded to the bonding surfaces of the film antenna units 10A and 10B at the flat surface parts 25e and bonded to the bonding surface of the bonding member 40 on the window glass 80 side at the flat surface part 25d.

Thus, the film antenna units 10A and 10B can be prevented from peeling off from the window glass 80.
  • the antenna elements 12A and 12B include the end portions 12A1 and 12B1 which do not contact with the films 11A and 11B, respectively, and the end portions 12A1 and 12B1 are electrically connected to the antenna element connecting parts 34 of the circuit board unit 30 by soldering. Thus, it is possible to further avoid bad electrical connection between the film antenna units 10A and 10B and the circuit board unit 30.
  • the antenna elements 12A and 12B are copper wires. Thus, it is possible to easily expose and solder the end portions 12A1 and 12B1 of the antenna elements 12A and 12B which do not contact with the films 11A and 11B.
