Zusammenfassung:	Provided is a laminated polyester film that exhibits excellent scratch recovery and contamination resistance and suits a molding application. A laminated film having a layer (A) on at least one side of a base film, wherein the resin contained in the layer (A) has (1) a (poly)caprolactone segment and (2) a urethane bond, and, in measurement using a micro hardness tester, the maximum displacement amount in the thickness direction of the layer (A) is 1.0 to 3.0 µm and the creep displacement amount in the thickness direction of the layer (A) is 0.2 to 0.5 µm when a load of 0.5 mN is applied for 10 seconds, and the permanent displacement amount in the thickness direction of the layer (A) is 0.3 to 0.65 µm when the load is released to 0 mN.
