An information carrier in which the substrate, having a signal-forming portion for forming signals corresponding to specific information, is attached to a base material having a transfer portion for transferring signals. The specific information is recognized using signals transferred from the signal-forming portion through the transfer portion. The surface attached to the substrate is the surface for attaching the carrier and substrate to an object. When the information carrier is peeled off the object, the substrate remains on the object, thereby separating the substrate and the base material. Accordingly, the signals from the signal-forming portion are no longer transmitted to base portion.
