The invention provides a laminate of an inorganic layer, a resin layer, and a coupling agent treatment layer interposed therebetween, which different delamination strengths between the inorganic layer and the resin layer to form a prescribed pattern. The invention also provides a production method comprising (1) treating an inorganic layer with a coupling agent; (2) performing a patterning process to form strong adhesion sections and easily separated sections; and (3) forming a resin layer by drying and heat-treating a coated solution layer obtained by coating a resin solution or a resin precursor solution onto the surface of the inorganic layer that was treated with a coupling agent and then patterned. |
