Claim:
1. A method for producing an electronic device, the method comprising: providing a supporting substrate; forming a release layer containing a metal or a metal oxide on the supporting substrate; and applying a resin material to the release layer to form a resin substrate including a front surface region opposite the release layer and a rear surface region in contact with the release layer, forming an electronic element on the resin substrate; and mechanically peeling the resin substrate with the electronic element formed thereon from the release layer formed on the supporting substrate, wherein the resin material contains elemental fluorine, and a ratio of a compositional proportion of fluorine in the rear surface region of the resin substrate to a compositional proportion of fluorine in the front surface region of the resin substrate is 0.45 or less.
