Claim:
1. An antenna device comprising: a multilayer body including magnetic layers or dielectric layers that are stacked; and an outer coil conductor that has a winding axis extending in a direction perpendicular or substantially perpendicular to a stacking direction of the multilayer body, the outer coil conductor being disposed so as to extend around a periphery, or a portion of the periphery, of the multilayer body; wherein an inner coil conductor is provided within a winding area of the outer coil conductor, the inner coil conductor having a winding axis extending in a direction perpendicular or substantially perpendicular to the winding axis of the outer coil conductor; the outer coil conductor has a structure that defines and functions as an antenna, and the inner coil conductor has a structure that defines and functions as an inductor; and at least a first end of the outer coil conductor and an end of the inner coil conductor are connected to each other.
