<p>PURPOSE: To obtain a thin, inexpensive non-contact type IC card by a method wherein an antenna coil is formed by overlapping a print coil formed on a thin plastic film in a plurality of layers. CONSTITUTION: On a surface of a print coil layer provided with a print coil (a first layer) formed by etching an aluminum-plastic film, an IC and a chip condenser are mounted. On the surface, a print coil layer is laminated, which is provided with a print coil (a second layer) formed by etching an aluminum- plastic film, a connecting hole on a part of the print coil, and a relief hole on a position corresponding to the IC and the chip condenser as well as coated with an adhesive on the back surface thereof. The print coil (the first layer) is connected to the print coil (the second layer) with the conductive adhesive. Lastly, plastic films each coated with an adhesive are laminated as upper and lower layers for forming a non-contact type IC card. In this manner, a thin, inexpensive, non-contact type IC card is obtained.</p> |
