PROBLEM TO BE SOLVED: To provide an antenna device which allows for reliable connection between a feed line in element and a feeding section, while simplifying the connection structure thereof.SOLUTION: An antenna device includes a feed line in element 421 and an antenna element 42 having a radiation element formed on a dielectric substrate 420, and a tri-plate line consisting of first and second ground plates 31, 32 and a central conductor 33. A first hole having a first facing surface facing the feed line in element 421 via a predetermined space 31a in the inner surface, and a second hole communicating with the first hole are formed in the first ground plate 31. The second hole includes, in the inner surface thereof, a restricting surface for restricting movement to the first facing surface side of the dielectric substrate 420. |
