Abstract
In a laminated film, a resin substrate, an organic/inorganic multilayer, and a silver-containing metal layer having a thickness of 20 nm or less are laminated in this order, an anchor metal diffusion control layer having a Hamaker constant of 7.3×10−20 J or more is provided on the surface of the inorganic layer, an anchor region containing an oxide of an anchor metal having a surface energy which has a smaller difference with a surface energy of the silver-containing metal layer than a surface energy of the anchor metal diffusion control layer is provided between the anchor metal diffusion control layer and the silver-containing metal layer, and a cap region containing an oxide of the anchor metal is provided on a surface of the silver-containing metal layer that is opposite from a surface on a side closer to the anchor metal diffusion control layer.
