Abstract
Abstract An electromagnetic interference suppressing body is provided for suppressing electromagnetic interference by undesirable electromagnetic waves. The body can have 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 circuit board electronic equipment and in a hybrid integrated circuit element having an active element and a passive element mounted on a circuit board.
