Abstract
Disclosed herein is a wiring panel constructed with a substrate; an electrically conductive member laminated on the substrate and principally composed of copper; and an insulating member composed of an organic substance, wherein a very small amount of a non-metallic element is incorporated into the electrically conductive member, and a very small amount of a metal element is incorporated into the insulating member. Also disclosed herein is a method for producing a wiring panel constructed with a substrate, an electrically conductive member provided on the substrate and composed of copper as the principal constituent, and an insulating layer of an organic substance covering the conductive member, which comprises steps of: applying onto the surface of the electrically conductive member a surface-reforming layer which functions to suppress electron transfer through the surface of the electrically conductive member, and thereafter forming the organic insulating layer on the electrically conductive member.
