An information recording medium includes a base material having an antenna and an electronic part substrate having an information recording circuit and attached to the base material. The antenna of the base material is electrically connected to the information recording circuit of the electronic part substrate. The surface onto which the electronic part substrate is attached is made a surface to be attached to a management object (commodity). On this electronic part substrate, there is formed an adhesive layer having a greater adhesive force with respect to the object than the adhesive force between the electronic part substrate and the base material. Thus, when the information recording medium is peeled off from the object, the electronic part substrate remains on the object. That is, it is possible to surely prevent injustice that an information recording medium used for (attached to) a commodity is used to another commodity and surely hold information security of the information recording medium. |
