Provided is a method for producing a wired circuit board in which a first preparation step of preparing a first substrate having an insulating layer and a conductive layer disposed on one surface of the insulating layer; a second preparation step of preparing a second substrate having a metal layer; a bonding step of laminating the first substrate and the second substrate so that the conductive layer and the metal layer are in contact with each other, and metal-bonding the conductive layer and the metal layer; and a patterning step of forming a conductive pattern on the other surface of the insulating layer are carried out.
