<p>PROBLEM TO BE SOLVED: To provide a laminated wiring board capable of easily changing the circuit constant. SOLUTION: In a laminated substrate 1 in the four-layer structure, having the top and bottom layers of first and second insulating layers 21 and 22 and laminating first and second dielectric layers 31 and 32 between them, conductor layers 51 and 54 are arranged facing, so as to sandwich the first or second dielectric layer 31 or 32 and three kinds of capacitors 61-63 are formed. Also these respective capacitors 61-63 and surface lands 41-43 formed on a surface 1a of the laminated substrate 1 are connected via a via hole 7. Then, by selecting any one of the surface lands 41-43, desired one of the capacitors 61-63 can be selected.</p> |
