Abstract
A method of fabricating electronic parts is provided which is capable of forming fine patterns with high accuracy as well as easily fabricating a multilayered structure of a conductor pattern with high performance. The disclosed method includes the steps of forming a pattern on a surface of a flexible resin sheet by laser process, and then forming a release layer on the surface of the thus obtained pattern, thereby forming an intaglio plate. Next, the intaglio plate is filled with Ag paste, dried and laminated onto an insulating substrate, on which a thermoplastic resin layer is formed. Thereafter, the intaglio plate is peeled from the substrate so that the pattern of the paste is transferred thereon, and a conductor pattern is formed. Further, an insulating layer is formed to cover the conductor pattern and another conductor pattern is formed on the insulating layer, thereby forming a multilayered structure.
