Abstract
Disclosed is a method of forming an electrically conductive circuit comprising the steps of: preparing a transferring paper in which an assembly of electrically conductive foil carrying a predetermined pattern and an insulating layer containing glass frit and an overcoat layer consisting of a resin film having good burning property are provided on a transferring paper covered with a paste layer; removing an integral structure of the conductive foil, the insulating layer, and the overcoat layer from the transferring paper; transferring the removed integral structure onto a substrate; and burning the substrate with the integral structure set thereon at a temperature where the glass is soften. According to this method, it is possible to eliminate transformation or damage of a conductive foil where a conductive foil is singly disposed on a substrate.
