Abstract:
1. An antenna device comprising: an antenna coil, the antenna coil comprising: a flat conductor adjacent to the antenna coil, wherein a gap is provided between the antenna coil and the flat conductor, first and second conductor portions of the coil conductor are disposed in positions that do not overlap each other in a plan view of the magnetic core when viewed in a direction perpendicular to the first flat main surface of the magnetic core, the first conductor portion being adjacent to the first flat main surface of the magnetic core, the second conductor portion being adjacent to the second flat main surface of the magnetic core, the first flat main surface of the magnetic core faces a plane extending through a surface of the flat conductor, the antenna coil is provided such that the first conductor portion is located adjacent to an end portion of the flat conductor in a plan view of the flat conductor and the antenna coil, and the antenna coil substantially overlaps the flat conductor in the plan view of the flat conductor and the antenna coil except for an end portion of the antenna coil on the first conductor portion side of the antenna coil.
