The invention provides an electromagnetic wave shielding material (10) for FPC, wherein the peeling phenomenon due to water vapor generated during the intense heating process is avoided. Meanwhile, the electromagnetic wave shielding material is in the form of a soft film and is excellent in electromagnetic wave shielding performance and bending property even after being subjected to severe bending treatment repeatedly. According to the technical scheme of the invention, one surface of a supporting film (6) is orderly laminated with a substrate (1) composed of a resin film coated with a dielectric medium, a film adhesive layer (2), a conductive paste layer (3) and a conductive adhesive layer (4). The water vapor transmission rate of the substrate is larger than 500g/m2 per day. |
