Abstract
A laminate structure is disclosed that has a region having high surface free energy and a region having low surface free energy that are well separated, has high adhesiveness between an underlying layer and a conductive layer, and can be formed easily with low cost. The laminate structure includes a wettability-variable layer including a first surface free energy region of a first film thickness and a second surface free energy region of a second film thickness, and a conductive layer formed on the second surface free energy region of the wettability-variable layer. The second film thickness is less than the first film thickness and the surface free energy of the second surface free energy region is made higher than the surface free energy of the first surface free energy region by applying a predetermined amount of energy on the second surface free energy region.
