Abstract
A circuit-like metallic foil sheet for resonant tags and the like, and a process for fabricating the same. The circuit-like metallic foil sheet is fabricated by a process comprising: fabricating a laminate by adhering, to a carrier sheet such as a paper or a plastic film, a metallic foil whose surface is coated with hot-melt adhesive resin film, using an adhesive whose adhesion force decreases by heating; stamping out the metallic foil of the laminate to provide thereto a predtermined circuit-like pattern using a stamping die; superposing the metallic foil side of the laminate on a support such as a plastic film: and trasnferring the circuit-like metallic foil to the surface of the support by heating the circuit-like pattern from the support side or the carrier sheet side. A circuit board comprising a resonant circuit or a printed wiring circuit can be obtained with high precision without employing an etching process in which chemicals are used.
