ABSTRACT:
A method of producing a wired circuit board includes preparing a metal supporting board, forming a metal foil on the metal supporting board, forming an insulating layer on the metal foil to expose an unneeded portion of the metal foil, etching the unneeded portion using the insulating layer as an etching resist, and forming a plurality of wires on the insulating layer.
