An electromagnetic interference suppressing body is provided for suppressing electromagnetic interference by undesirable electromagnetic waves. The body includes a conductive support element and a non-conductive soft magnetic layer provided on at least one surface. The electromagnetic interference suppressing body may be used in an electronic equipment comprising a circuit board and an active element mounted on the circuit board, and is interposed between the circuit board and the active element so as to suppress the interference by an induction noise generated from the active element. The electromagnetic interference suppressing body may also be used in a hybrid integrated circuit element having an active element and a passive element mounted on a circuit board. The hybrid integrated circuit element is covered with and sealed by a non-conductive layer and the electromagnetic interference suppressing body overlying an outer surface of the non-conductive layer.

For reducing undesirable radiation of a signal, a shield cable assembly includes a cylindrical magnetic member fitted around a shielded-conductor cable to which a shielded joint is electrically and mechanically connected. An inner insulator is mounted in a connecting portion between the cable and the joint so as to support electrical contacts of the joint together with extened portions of insulated conductors of the cable, in electrical connection with one another. An electrical conductive coating is applied on the surface of the inner insulator, and is electrically connected to a cable shield of the cable. As a result, the magnetic member and the coating cooperate to reduce undesired radiation of signals from the assembly. In addition, an outer insulator encloses the inner insulator and the magnetic member, thus to connect mechanically the inner insulator with the magnetic member.
