Abstract: A laminated film has a layer (A) on at least one side of a base film, wherein 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, a maximum displacement amount in a thickness direction of the layer (A) is 1.0 to 3.0 μm and a 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 a 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.
