ABSTRACT:
There is provided a printed circuit board including (a) at least one dielectric layer, (b) at least two metal layers one of which acts as a ground layer, another one of which acts as a power-supplying layer, and the others of which, if any, act as a wiring layer in which a signal pattern is formed, the dielectric layer and the metal layers being alternately formed one on another, and (c) at least one resistor disposed at a marginal end of the printed circuit board between the ground layer and the power-supplying layer, the resistor having a function of disallowing current communication between the ground layer and the power-supplying layer. The above-mentioned printed circuit board prevents fluctuation in a voltage between ground and a power-supply, and further prevents unintentional electromagnetic interference and circuit malfunction caused by invasion of external electromagnetic field thereinto.
