摘要： The present invention enables production of an aromatic polyester film having no surface defect and a uniform thickness, while achieving a high productivity, by allowing a molten film of an aromatic polyester to adhere onto a rotating cooling drum to cool the molten film. The molten film has electrical properties characterized by a relatively small AC volume resistivity and has excellent basic properties necessary for adhering onto the rotating cooling drum.
