Abstract
For protecting information stored in an RFID chip and ensuring its authenticity, radio communication between the RFID chip and an external terminal is positively interrupted when a seal type RFID tag including the RFID chip is peeled from an adherend, while ensuring solidity integrity when the RFID tag is put on the adherend. In the seal type RFID tag which includes the RFID chip fixed on a mounting surface of a base member having an adhesive layer applied thereto and which is put on the adherend by using the adhesive layer, an antenna formed on a main surface of the RFID chip is embedded in adhesive layers together with the RFID chip and an adhesive bonding strength between the antenna and the adhesive layer is made greater than a joining strength between the antenna and the RFID chip.
