Abstract
An antenna device includes a plurality of coil antennas each including a coil conductor wound around a winding axis and a planar conductor including a first edge and a second edge between which a corner or a curved portion is interposed. A first coil antenna is arranged at a position along the first edge of the planar conductor at which one coil opening thereof is superposed with the planar conductor when viewed in plan and that is close to the corner or close to the curved portion. A second coil antenna is arranged at a position along the second edge of the planar conductor at which one coil opening thereof is superposed with the planar conductor when viewed in plan. The first coil antenna and the second coil antenna are connected such that magnetic flux generated by the first coil antenna and magnetic flux generated by the second coil antenna are in phase with each other in a direction toward the outside with the first edge and the second edge of the planar conductor defining boundaries.
