Abstract

A separation layer is formed over a substrate having a depressed portion, using a silane coupling agent; a conductive layer and an insulating layer that covers the conductive layer are formed in the depressed portion over the separation layer; and a sticky member is attached to the insulating layer, then the conductive layer and the insulating layer are separated from the substrate. Alternatively, after these steps, a flexible substrate is attached to the conductive layer and the insulating layer.
