To provide a low-cost article having a simple constitution and prevented from doing fraud such as integrally stripping an RF-ID (radio- frequency identification) media from the article or sticking the RF-ID media to another article.

This article is provided with, at least, a conductive pattern with a connecting conductive part in a substrate and disposed with an IC chip mounting body, which is formed by mounting an IC chip on the connecting conductive part, by directly fixed to a prescribed position, or disposed with an antenna part composed of a conductive pattern, which is formed of an antenna conductive part and a connecting conductive part positioned in the end part of the antenna conductive part, by directly fixed to a prescribed position. The IC chip mounting body or the antenna part is detachably formed with the antenna part or the IC chip mounting body, which is formed into the RF-ID media by assembled with the antenna part or the IC chip mounting body.
