Abstract
A multi-layer circuit board comprises: an insulating layer having upper and lower surfaces thereof, and wiring patterns arranged on the upper and lower surfaces of the insulating layer. A ferroelectric layer has a dieletric constant larger than that of the insulating layer and has upper and lower surfaces. The ferroelectric layer is arranged in the insulating layer in such a manner that the upper and lower surfaces of the ferroelectric layer coincide with the upper and lower surfaces of the insulating layer, respectively. A pair of electrode films are formed on the upper and lower surfaces of the ferroelectric layer, respectively, to define a capacitor incorporated in the multi-layer circuit board.
