To provide a polyester film which includes a polyester substrate and a release layer and exhibits a small amount of migration of a component derived from the release layer to a member when the member is arranged on the release layer and peeled off.SOLUTION: The polyester film includes the polyester substrate and the release layer containing substantially no particles. The polyester substrate contains at least one of a titanium element and an aluminum element. The release layer does not contain a platinum element and contains a cured product of a first compound and a second compound. The first compound is a curable compound, and the second compound is an organic crosslinking agent capable of reacting with the curable compound.SELECTED DRAWING: None 【課題】 ポリエステル基材と剥離層とを含み、剥離層上に部材を配置してその部材を剥離した際に、部材へ剥離層由来の成分の移行量が少ない、ポリエステルフィルムを提供。【解決手段】 ポリエステル基材と、実質的に粒子を含まない剥離層とを含むポリエステルフィルムであって、ポリエステル基材が、チタン元素及びアルミニウム元素の少なくとも一方を含み、剥離層が白金元素を含まず、第１化合物と第２化合物との硬化物を含み、第１化合物が硬化性化合物であり、第２化合物が硬化性化合物と反応可能な有機架橋剤である、ポリエステルフィルム。【選択図】なし
