Zusammenfassung:	Provided is a layered body including glass and a polyamic acid heat-cured product that is readily releasable from an inorganic substrate after being heated at 250°C. A layered body including an inorganic substrate and a polyamic acid heat-cured product, the layered body being characterized by a weight average molecular weight of 30,000 or greater for the polyamic acid, and a peel strength of 0.3 N/cm or weaker between the polyamic acid heat-cured product layer and the inorganic substrate, after the layered body has been heated at 250°C.
