Abstract
A method for producing a wired circuit board includes the steps of preparing a metal supporting layer, forming an insulating layer on the metal supporting layer so as to form an opening, forming a conductive thin film on the insulating layer and on the metal supporting layer that is exposed from the opening of the insulating layer, heating the conductive thin film, forming a conductive pattern on the conductive thin film that is formed on the insulating layer, and forming a metal connecting portion to be continuous to the conductive pattern on the conductive thin film that is formed on the metal supporting layer exposing from the opening of the insulating layer.
