The purpose of the present invention is to provide a white aromatic polyester film that does not give rise to cutting debris at the time of cutting the aromatic polyester film. This aromatic polyester film comprises: a cyclic carbodiimide compound that includes a carbodiimide group in the ring skeleton thereof and that has, in the molecule thereof, at least one cyclic structure in which the first nitrogen and the second nitrogen of the carbodiimide group are bonded by a bonding group, or a ketenimine compound; fine particles; and an aromatic polyester resin. This aromatic polyester film is characterized in that: the content by percentage of the cyclic carbodiimide compound or the ketenimine compound is 0.1-5 mass% to the mass of the aromatic polyester resin; the particle size of the fine particles is 0.1-10 µm; the content by percentage of the fine particles is 1-10 mass% to the mass of the aromatic polyester resin; a portion of the fine particles is aggregated; and the aggregation rate of the fine particles is 10-50%. |
