Abstract

The present invention relates to a laminated film comprising a substrate and a functional layer provided on one surface side of the substrate. The functional layer contains an antistatic agent. The functional layer does not contain particles having an average particle diameter of 0.1 μm or more. When the thickness of the functional layer is Tf and the maximum depth of recesses and protrusions on the surface of the laminated film on the side opposite from the substrate-side surface, among the two surfaces opposite of each other of the laminated film, is Df, Tf > Df > 0.1 μm is satisfied.
