1. A printed-circuit board comprising:
- an insulating layer;
a wide electric conductor pattern formed into a plane configuration having a recessed section in part so as to make up a ground pattern or a power supply pattern on said insulating layer; and
an additional electric conductor electrically connected with said wide electric conductor pattern so as to close said recessed section.

Abstract
Occurrence of EMI is reduced without a sharp increase of the manufacturing cost by suppressing a common mode current stably. There is provided a disclosed printed-circuit board being adapted such that a width of an outer edge section of a T-shaped pattern is widened so as to surround a recessed section with a frame-shaped additional electric conductor by electrically connecting the frame-shaped additional electric conductor with the T-shaped pattern making up a ground pattern so as to close the recessed section.
