Abstract
An antenna device includes a first coil wound in one direction and a second coil disposed adjacent to the first coil and wound in a direction opposite to the winding direction of the first coil and having conductor openings at the centers of wound coils, and a magnetic core. The magnetic core is inserted into the conductor opening of the first coil and the conductor opening of the second coil. A portion of a conductor line forming the first coil positioned farther away from the second coil than a portion of the conductor line forming the first coil positioned closer to the second coil, and a portion of a conductor line forming the second coil positioned farther away from the first coil than a portion of the conductor line forming the second coil positioned closer to the first coil, are disposed along the first main surface of the magnetic core.
