Title: COIL ELEMENT, ANTENNA DEVICE, CARD-TYPE INFORMATION MEDIUM, WIRELESS IC DEVICE AND ELECTRONIC DEVICE
Abstract:
This coil element (101) is provided with a first substrate (1) having a first main surface (VS1), a second substrate (2) having a fourth main surface (VS4), first conductor patterns (11a-11g) formed on the first substrate (1), second conductor patterns (21a-21g) formed on the second substrate (2), a plurality of first bonding wires (31), and a plurality of second bonding wires (32); and this coil element (101) constitutes a coil. The second substrate (2) is arranged such that the fourth main surface (VS4) faces the first main surface (VS1). The first conductor patterns (11a-11g) are connected to first ends of the second conductor patterns (21a-21g) via the first bonding wires (31), while being connected to second ends of the second conductor patterns (21a-21g) via the second bonding wires (32).
