An RFID tag is provided as a wireless communication device that transmits and receives a communication signal. The RFID tag includes a base material, a conductor pattern including an antenna pattern provided at the base material, and a discharge auxiliary electrode. The discharge auxiliary electrode is disposed at a position where the discharge auxiliary electrode overlaps or is close to the antenna pattern in planar view, and lowers a dielectric breakdown voltage between two different opposed portions on the conductor pattern. With this configuration, ignition and combustion is prevented even in a situation in which the RFID tag is subjected to high-frequency power for heating a food item while attached to the food item.
