CONDUCTIVE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a conductive substrate having excellent conductivity and adhesion.SOLUTION: The conductive substrate is a laminate which comprises a porous copper layer on one surface side of an insulation resin base material, where holes of the copper layer at least partially include a base material-derived component-containing area containing a component derived from the insulation resin base material, and the copper layer has a volume resistivity of 20 μΩ/cm or less.SELECTED DRAWING: Figure 1
