<p>Disclosed is an antenna device wherein a coupling electrode can be freely disposed without being limited by the position where a transmitting/receiving circuit maintaining excellent connectivity is disposed, while achieving a high production efficiency. The antenna device is provided with: a printed board wherein ground (2) is formed on one surface, and a signal line (3) having signals transmitted thereto is formed on the other surface, with a base material (4) between the ground and the signal line; the coupling electrode (8), which is composed of a conductor having substantially a flat surface, and which performs communication by being coupled, by electromagnetic field coupling, with the electrode of other antenna device disposed on a position facing the coupling electrode; and an electrode post (7) which electrically connects together the signal line (3) formed on the printed board, and the coupling electrode (8) by having the signal line and the printed board at a predetermined interval in the direction of the thickness of the printed board. A connecting terminal section (9) that can be electrically connected with the transmitting/receiving device, which performs signal transmission/reception processing, is formed on one end of the signal line (3), and at least a terminal forming section (1a), which has the connecting terminal section (9) formed thereon, has flexibility in the printed board.</p> |
