An antenna device (10) comprises a coil antenna (11A) for a first non-contact transmission system, and a coil antenna (11B) for a second non-contact transmission system. The coil antenna (11A) has a coil conductor (12A), and a coil opening (13A) surrounded by the part in which current flows in the same peripheral direction as the coil conductor (12A) when seen in plane view. The coil antenna (11B) has a coil conductor (12B), and a coil opening (13B) surrounded by the part in which current flows in the same peripheral direction as the coil conductor (12B) when seen in plane view. When seen from plane view, the coil opening (13A) has openings (132A and 133A) that do not overlap the coil opening (13B), and that are divided from each other by the coil opening (13B).
