Abstract
A circuit chip having a loop-shaped antenna coil on a main surface and a tag sheet having an antenna pattern on a main surface are prepared, and the circuit chip is mounted on the main surface of the tag sheet so as not to place over the antenna pattern. The circuit chip is placed closely to the antenna pattern, and at least the half of the main surface is desirably faced against the antenna pattern. Thus, signals and/or power can be securely exchanged between the circuit chip (or antenna coil) and the antenna pattern. Therefore, a high-performance and rigid RFID tag can be obtained by roughly aligning the circuit chip and the tag sheet.
