PROBLEM TO BE SOLVED: To provide a resin substrate with a support substrate in which troubles do not occur during the peeling of the resin substrate by lowering the adhesive strength between the support substrate and the resin substrate.SOLUTION: There is provided a resin substrate with a support substrate including a support substrate 2, a release layer 3 disposed on the support substrate 2 and comprising metal or metal oxide, and a resin substrate 4 disposed on the release layer 3, and in which the resin material constituting the resin substrate 4 comprises elemental fluorine and, in the resin substrate 4, the ratio of the fluorine composition ratio of the rear surface region R on the side in contact with the release layer 3 to the fluorine composition ratio of the front surface region F on the side opposite to the release layer 3 is 0.45 or less. |
