摘要： In an LC-type dielectric filter, an inductor is formed on the uppermost or outermost insulation or dielectric layer and electrically connected at the opposite ends thereof to an upper electrode and a lower electrode which cooperate with a thin film dielectric layer to constitute a capacitor, by means of conductive vias. A method of adjusting a frequency of an LC-type filter is also provided. By the method, an optimum inductance for an inductor is calculated based on a measured capacitance and a desired frequency of the filter, and a pattern of the inductor which is capable of attaining the optimum inductance is selected from a group of predetermined patterns which differ in inductance. The inductor is formed on the outermost dielectric layer in such a manner as to have the selected pattern.
