摘要:
The non-contact information recording medium is made by forming the antenna circuit and connecting it to the IC module through connection terminals at the same time. This provides a high degree of freedom of patterning of the antenna circuit. The antenna circuit is formed on a recording substrate, in which an IC module has been embedded. A foil-bonding resin layer is formed on the connection terminals of the recording substrate, with a toner containing a binder resin by an electrophotographic method. Then a conductive foil is brought into contact with the foil-bonding resin layer to bond the foil to the resin layer, to connect the antenna circuit to the connection terminals and form the antenna circuit composed of the conductive foil.
