<p><P>PROBLEM TO BE SOLVED: To build a capacitor element having a capacity equal to the designed one in a multi-layer circuit board, regardless of the largeness of the lower electrode of the capacitor element. <P>SOLUTION: The multi-layer circuit board 25 with a built-in capacitor element includes first and second capacitor elements 23a, 23b in which lower electrodes 15a, 15b, a dielectric layer 18, upper electrodes 19a, 19b are laminated sequentially. The first and second capacitor elements include dummy patterns 22a, 22b, which are not connected with the lower electrode and are formed around the lower electrode. There is a relation of D1<D2 when S1>S2, and D1>D2 when S1<S2, where S1, S2 are each electrode area of the lower electrodes in the first and second capacitor elements, and D1, D2 are each area of dummy patterns of the first and second capacitor elements. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
