ABSTRACT:
A shield construction for electrical devices which comprises a conductive thin film mounted at least one of the surface of electrical devices. The shield construction is connected with ground leads of a electrical devices or the ground plane of the circuit board. The shield construction prevents the radiation of undesired waves from the electrical devices. As a result, the deterioration of the receiving sensitivity and noise generation becomes negligibly small even in the weak electric field area.
