Disclosed herein is a Printed Circuit Board (PCB) having embedded resistors and a method of manufacturing the same, in which contact pads are formed by filling via holes formed on electrode pads with oxidation-resistant conductive material, and resistors are formed on the contact pads. Accordingly, erosion that occurs between the electrode pads and the resistors can be prevented using the contact pads made of oxidation-resistant conductive material, and connections between circuits also can be realized. Furthermore, resistors are formed on a flat plane without any difference in height, attributable to the electrode pads, and thus differences between the resistance values of the built-in resistors can be greatly reduced.
