ABSTRACT:
The present invention relates to an RFID tag and is provided with a function of detecting peeling while maintaining a good antenna characteristic. A first conductive pattern includes two extending sections extending from an IC chip, each end of which is connected to the IC chip, and a correction pattern for antenna characteristic correction which bypasses the IC chip and connects the two extending sections, and a peeling detection pattern is formed in an area enclosed by the two extending sections and the correction pattern.
