Electromagnetic wave shielding film and method for producing the same

Abstract

An electromagnetic wave shielding sheet 1 comprises a transparent substrate 11, and a first anticorrosive layer 23A, a first blackening layer 25A, a metal layer 21, and a second anticorrosive layer 23B that are successively formed on the transparent substrate 11 through an adhesive layer 13. A second blackening layer 25B is formed so that it fully covers the side faces of the first anticorrosive layer 23A, the first blackening layer 25A, the metal layer 21, and the second anticorrosive layer 23B, as well as the front face of the second anticorrosive layer 23B. At least either of the first anticorrosive layer 23A and the second anticorrosive layer 23B contains one or more metals selected from nickel, chromium, and silicon, and also zinc and/or tin when it is initially formed, and the zinc and/or tin is removed from the first anticorrosive layer 23A and/or the second anticorrosive layer 23B in an intermediate steps.
