CONDUCTIVE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a conductive substrate excellent in conductivity and adhesion.SOLUTION: A conductive substrate is a laminate where an insulation resin layer and a porosity copper layer are arranged in this order on one face side of a substrate. The porosity copper layer includes an insulation resin layer derived component containing region on at least a part of the porosity copper layer. The maximum thickness of the insulation resin layer derived component containing region is larger than 100 nm.SELECTED DRAWING: Figure 1
