Abstract
The present invention provides an RFID tag that is very effective in preventing fraudulent uses. The RFID tag includes a base, an antenna pattern provided on the base, a breakdown pattern provided on the base, a circuit chip connected to both the antenna pattern and the breakdown pattern, and a cover that is bonded to the base in a strippable condition so as to cover the antenna pattern, the breakdown pattern and the circuit chip and is caused to come off together with all or a part of the breakdown pattern during stripping from the base. The breakdown pattern is transparent, or the cover conceals a remaining part of the breakdown pattern, or the breakdown pattern has a specific part that produces predetermined electrical properties and the cover conceals the specific part.
