Figure 15 represents the wireless IC module 630 of embodiment 5, and Figure 15 (A) is top view, and Figure 15 (B) is look up figure.
The wireless IC module 630 of embodiment 5 is same as in Example 3, including wireless IC 230, multiple wire electrode 830 and public electrode 470.But, in wireless IC module 630, as different from Example 3, two ends coupling part, multiple wire electrode 830 and public electrode 470 not shown in Figure 15 do not turn on connection.That is, wireless IC module 630 has two public electrodes 470, and these public electrodes 470 carry out Capacitance Coupled, thus constitute ring electrode 730.As shown in Figure 15 (B), two public electrodes 470 are overlapping one another by insulating barrier at the back side of substrate 330, carry out Capacitance Coupled.
