An RFID tag is provided that transmits and receives a communication signal. The RFID tag includes a base material, antenna patterns provided on the base material, an RFIC package that is a feeding circuit connected to the antenna patterns, and an ignition protection member provided on the base material or the antenna patterns. Moreover, the ignition protection member contains moisture, such that ignition and combustion can be prevented even in a situation where the RFID tag is subjected to high-frequency power for heating a food item while attached to the food item or the like.
