<p>PROBLEM TO BE SOLVED: To provide a release film excellent in air releasability in which a release layer is hardly shifted to an adherend.SOLUTION: There is provided a release polyester film which is a release film obtained by forming a resin layer on at least one surface of a polyester film substrate, where the resin layer contains a silicone-based polymer having an epoxy group and a melamine resin, the residual adhesion ratio is 90% or more, the centerline average roughness (SRa) of the resin layer is more than 20 nm and the peeling strength of the resin layer is 0.01 to 0.10 N/cm.</p> |
