Zusammenfassung:An antenna device (10A, 10B) comprises: a magnetic core (20A, 20B); a bobbin (30A, 30B) housing the core (20A, 20B); a coil (50A, 50B) of wire (51A, 51B) wound around the bobbin (30A, 30B), and a terminal mounting part (35A, 35B), to which a terminal (60A, 60A1, 60A2, 60B, 60B1, 60B2, 60B3) is attachable, provided at a first end of the bobbin. The coil (50A, 50B) includes: a tight winding portion (53A, 53B) at the first end of the bobbin (30A, 30B); and a loose winding portion (54A, 54B) at a second end of the bobbin (30A, 30B). The tight winding portion (53A, 53B) is located closer to the terminal mounting part (35A, 35B) than is the loose winding portion (54A, 54B).
