Abstract
For sufficiently shielding an undesired electro-magnetic wave from penetrating into a communication apparatus, for instance, a car telephone through stray coupling, or leaks therefrom, an electronic circuit substrate and a case of the communication apparatus are formed of flat plates which consist of insulating material comprising magnetic material. One side surface of the flat plates are covered with conductive films. The communication apparatus itself is accommodated in the case and an electric power source connecting cable is wrapped by a similar arrangement, so as to remarkably reduce obstructions caused by undesired waves and other communications in comparison with the conventional arrangement.
