To provide an electromagnetic wave shielding film for a PDhaving a low luminous reflectance even without providing a protective film, and a protective plate for a PDhaving a low luminous reflectance using the electromagnetic wave shielding film for a PDP. An electromagnetic wave shielding film 10, which comprises a substrate 11 and an electroconductive film 12, wherein the electroconductive film 12 has a multilayer structure in which (n+1) (wherein n is an integer of from 3 to 5) inorganic layers 12a having a refractive index of from 1.55 to 2.5 and n metal layers 12b are alternately laminated from the substrate 11 side; each inorganic layer 12a is a layer containing at least one member selected from a metal oxide, a metal nitride and a metal oxynitride; each metal layer 12b is a layer made of pure silver or a silver alloy; and the second to n-th metal layers from the substrate are thicker than the first metal layer from the substrate, is used.
