1. A shield film suitable for use in shielding a signal-transmitting circuit from signal-interfering electromagnetic noise, comprising:a metal layer, which is 2 ?m to 12 ?m thick;
an insulating layer, which is 1 ?m to 10 ?m thick and is disposed along and in contact with a first surface of the metal layer; and
an anisotropic conductive adhesive layer containing conductive filler with an average particle size of 2 ?m to 20 ?m, which anisotropic conductive adhesive layer is disposed along and in contact with a second, opposite surface of the metal layer;
wherein the shield film exhibits between 74 dB and 96 dB of attenuation of an electric field wave at 1 GHz, as measured using KEC method.
