The present invention is a film for prevention of electromagnetic interference and transmission of wireless signals. A conductive lamination is integrally attached to a preset position of a substrate and shaped as a film and a signal transceiver. The method of forming the film includes selecting a substrate and selecting a signal transmitting and receiving mode and a form of the conductive surface according to a specific need. A film-shaped signal transceiver and conductive lamination are integrally formed on a preset area of the substrate. By plating and/or coating, the present invention can form a conductive lamination on the substrate with both functions as a signal transceiver and a shield.
