A laminated film including a support substrate and a surface layer on at least one surface of the support substrate, the laminated film satisfying the following Conditions 1 to 3: Condition 1: the surface layer has a maximum displacement amount in a thickness direction of 1.50 µm or more, and the surface layer has a permanent displacement amount in the thickness direction of not more than 1.30 µm, as determined by a load-unload test method using a micro hardness tester under conditions of a maximum load of 0.5 mN and a retention time of 10 seconds; Condition 2: the surface layer has a relative storage elastic modulus at 100°C, as determined by a rigid body pendulum test method, that is higher than the relative storage elastic modulus at 25°C of the surface layer; and Condition 3: the surface layer has an elongation at break at 150°C, as determined by a tensile test method, of 50% or more. Provided is a laminated film satisfying formability, self-healing properties, design properties, and resistance to high shear. |
