PROBLEM TO BE SOLVED: To contribute to continuous productivity improvement because the amount of oligomer deposited from each film surface of a release film is as small as possible in each manufacturing process such as an adhesive application process, a drying process, and a release film bonding process. Providing a release film. SOLUTION: A polyester film has a coating layer containing an ammonium base-containing polymer, a polyethylene glycol-containing polymer and a crosslinking agent on both sides, and a release layer is laminated on at least one coating layer.
