<p><P>PROBLEM TO BE SOLVED: To provide a thin and flexible electromagnetic wave shield material for FPC having excellent flexing characteristics in which the electromagnetic wave shielding performance does not degrade even if severe bending operation is repeated. <P>SOLUTION: In the electromagnetic wave shield material 1 for FPC, a substrate 2 consisting of a dielectric is a flexible polyimide film having a thickness of 3-15μm, and an adhesive layer 3 and a conductive paste layer 4 are laminated sequentially on one side of the substrate 2. Preferably, the adhesive layer 3 is composed of an adhesive resin composition ensuring an adhesive force of the conductive paste layer 4 to the substrate 2 of 6 N/inch or higher, and having heat resistance of 240-260°C. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
