Abstract
Disclosed is a PCB including an embedded resistor and a method of fabricating the same. The PCB includes a plurality of circuit layers in which circuit patterns are formed. A plurality of insulating layers is each interposed between the circuit layers. The embedded resistor is made of a resistive material and received in a receiving hole formed in the plurality of circuit layers and the plurality of insulating layers such that walls defining the receiving hole extends from one of the circuit layers to another circuit layer. The receiving hole has a closed section, and a conductive material is plated on the opposite walls of the walls defining the receiving hole.
