Abstract
The present invention aims to provide an RFID tag capable of improving antenna efficiency with a simple configuration. Such an RFID tag includes: an antenna configured with a reader/writer; an IC chip to which the antenna is connected; a plurality of connection terminals inside outer peripheral edges of an insulating layer on which the antenna is formed; and an annular antenna-forming area on the entire periphery or substantially the entire periphery of the insulating layer. The antenna is formed into a loop in the antenna-forming area, with one of the plurality of connection terminals serving as a starting point and with one of the remaining connection terminals serving as an endpoint.
