ABSTRACT:
It is the object of the invention to suppress electromagnetic radiation caused by the ground potential of a printed-circuit board, which now becomes an important problem, as the bit-rate of digital signals increases. The ground-pattern of an electronic circuit mounted on the printed-circuit board is connected to the shield-case of an electronic circuit apparatus via a conductor-piece, noise generated by the electronic circuit is by-passed, and electromagnetic radiation of noise from a cable connected to the printed-circuit board via a connector can be suppressed.
