Abstract

A method for producing a circuit board includes providing a substrate on which a toner image formed of a thermoplastic toner has been formed and forming a conductive foil layer having a thickness of 0.1 μm to 2 μm on the toner image that has been formed on the substrate and then applying heat to the toner image and the conductive foil layer to form a wire constituted by conductive foil.
