<p>PROBLEM TO BE SOLVED: To achieve compaction without providing a dedicated antenna, and to facilitate impedance matching, in a printed wiring board or an electronic apparatus.SOLUTION: A printed wiring board with a wireless IC chip includes a wireless IC chip 5 for processing transmission and reception signals, and a printed wiring board 20. On the printed wiring board 20, a loop electrode 22 connected with the wireless IC chip 5, and a planar ground electrode 21 are formed, and the wireless IC chip 5 is mounted. On the printed wiring board 20, the loop electrode 22 is formed in the vicinity of the outer edge of the ground electrode 21. The wireless IC chip 5 is connected with the loop electrode 22, the loop electrode 22 is connected with the ground electrode 21 via an electromagnetic field, and the ground electrode 21 functions as a radiation plate.</p> |
