<p>PROBLEM TO BE SOLVED: To provide a release film having a high residual adhesion ratio and excellent flatness.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 20 nm or less and the peeling strength of the resin layer is 0.01 to 0.10 N/cm.</p> |
