Abstract
A flat, built-in resistor and capacitor has a substrate (10) made of dielectric material; a copper layer (12) formed on each surface of the substrate (10) and having an etched image (30) formed in each of the copper layers (12); a dielectric material layer (40) printed onto the copper layer (12) and filling up the etched image; and a resistance layer (50) printed onto the copper layer (12) and the dielectric material layer (40).
