Abstract:
A wireless IC device (101) having a coil antenna is provided with a first substrate (1), a first metal post (30), a second metal post (40), and a connecting conductor (50). First linear conductor patterns (10A, 10B) are formed on a first main surface (PS1) of the first substrate (1). The first metal post (30) and the second metal post (40) are disposed such that the first metal post and the second metal post extend in the normal line direction with respect to the first main surface (PS1) of the first substrate (1), and first ends (30E1, 40E1) of respective posts are connected to the first linear conductor patterns (10A, 10B), respectively. A first end (50E1) of the connecting conductor (50) is connected to a second end (30E2) of the first metal post (30), and a second end (50E2) of the connecting conductor (50) is connected to a second end (40E2) of the second metal post (40). A second end (10AE2) of the first linear conductor pattern (10A), and a second end (10BE2) of the first linear conductor pattern (10B) are power feeding ends.
