Summary:A method for precisely controlling resistance for a resistor-embedded printed circuit board is provided to manufacture a resistor with almost uniform resistance by planarizing a carbon ink filled between copper clad electrode pads. A method for manufacturing an embedded resistor(70') includes the steps of: forming copper clad electrode pads(20) constituting electrodes of the resistor on a substrate; filling the rectangular resistor with predetermined length and width on regions on which the resistor electrode pads are formed by carbon ink between the copper clad electrode pads; and planarizing the carbon ink filled between the copper clad electrodes by mechanically polishing the carbon ink to have the same height as those of the electrode pads.
