Abstract: An electroconductive adhesive tape used for electrical and electronic products to bond or fix an element to a support while maintaining an electrical conductivity between the element and support. The electroconductive adhesive tape includes a perforated synthetic film, two metal plating layers respectively formed on both surfaces of the synthetic resin film, and a conductive adhesive layer formed on one of the metal plating layers. Made to be very thin, the film has the advantage of being flexible and high in tensile strength in addition to showing excellent electrical conductivity. The metal plating layers are integratedly formed through the perforations of the synthetic resin film, maintaining excellent electrical conductivity. Thus, the electroconductive adhesive tape maintains a desired strength while exhibiting a high flexibility and a high bondability.

Abstract: An electrically conductive adhesive tape used for electrical and electronic products to bond or fix an element to a support while maintaining an electrical conductibility between the element and support. The conductive adhesive tape has a structure including a resin film, a metal layer formed over one surface of the resin film by depositing a conductive metal over the surface of the resin film, and a conductive adhesive layer coated over the metal layer. The metal layer has a net-shaped structure. In some cases, the metal layer may have a planar structure. The conductive adhesive tape has a very small thickness by virtue of its metal layer deposited to a very small thickness. Accordingly, the conductive adhesive tape maintains a desired strength while exhibiting a high flexibility and a high bondability, thereby exhibiting a superior conductibility. In the case in which the metal layer has a net-shaped structure, the tape has a structure having spaces where the metal layer does not exist. Where the tape is applied to a Braun tube, accordingly, there is no influence on an electron beam emitted from a deflection yoke while a desired conductibility is maintained. The manufacture of the tape is simple. By virtue of the conductibility, the tape of the present invention also has an elecromagnetic wave shielding function.
