Abstract: An electric field shielding apparatus used with an electrical device comprises a housing body at least partially surrounding the electrical device; and a conductive shield medium arranged with the shape of the housing body to at least partially surround the electrical device to substantially reflect electric field generated from the electrical device. The conductive shield medium is a thin conductive layer coated on interior surface of the housing body. Alternatively, the conductive shield medium is a conductive mesh placed against interior surface of the housing body. In addition, the conductive shield medium may be integrally mixed with the housing body to make the housing body substantially electrically conductive. In other words, the conductive shield medium may be in a powder form which is mixed with plastic power, the mixture of which is then heated and poured into an injection mold to form a housing body of an electric device. To effectively block or absorb the electric field generated from a device, the conductive shield medium is preferably grounded by being connected to a ground prong of a power outlet.
