The related art RFID tag includes a plurality of antennas for receiving radio waves, an IC part for performing signal processing on the received radio waves, and thermal fuses disposed on connecting parts between the antennas and the IC part. The thermal fuses are configured to melt by heat generated in the IC part while receiving radio waves exhibiting high signal levels, which may detach the antennas from the IC part. Since the antennas are irreversibly detached, excessive electric power supply to the IC part is terminated, which may prevent the IC part from being damaged by heat.
However, when the management of temperature rise in articles is attempted by utilizing such an RFID tag including the thermal fuses, the identifier of the RFID tag is not able to be read by a reader device after the temperature rises to melt the thermal fuses.
