An RFID tag that includes a radio IC chip, an antenna pattern, a matching circuit, a capacitive coupling member connected to the antenna pattern and capacitively coupled to a metal surface, and an insulating substrate. The antenna pattern includes a first antenna pattern connected to the radio IC chip with the matching circuit interposed therebetween and a second antenna pattern having one end connected to the radio IC chip with the matching circuit interposed therebetween and the other end connected to the capacitive coupling part. Moreover, the RFID tag includes a capacitive member between the first antenna pattern and the capacitive coupling part, and the antenna pattern, the capacitive coupling part, and the capacitive part are connected in a loop.
