Abstract
A wired circuit board that can provide a reduced transmission loss and an improved adhesion strength between a metal suspension board and a metal foil with a simple laminar structure, thereby ensuring improved long-term reliability. The wired circuit boardcomprises a metal suspension board, a thin metal filmformed on the metal suspension boardby sputtering or by electrolytic plating, a metal foilformed on the thin metal filmby electrolytic plating, an insulating base layerformed on the metal foiland the metal suspension board, and a conductive patternformed on the insulating base layeras a wired circuit pattern. The wired circuit boardmay include an insulating cover layerformed on the insulating base layerto cover the conductive pattern
