PROBLEM TO BE SOLVED: To provide a laminated polyester film that is excellent in an adhesion force with a layer used for various FPD applications after solving the problems of the conventional technology by reducing the number of defects of coating cissing by the thinning of the thickness of a laminated film, and also, by providing a laminated film, having excellent easy adhesion with respect to a hard coat or the like, on one face or both faces of the laminated polyester film by reducing an addition amount of a surfactant. SOLUTION: The laminated polyester film has a laminated film, of which the product nd of a film thickness d and a refractive index n is 15-35 nm, on at least one side of a polyester layer (a base-material layer).
