Zusammenfassung:PROBLEM TO BE SOLVED: To provide a component built-in type multilayer board which is suitable for building components of different heights therein. SOLUTION: A metal core layer formed by bonding metal layers 30-1 and 30-2 is used to build the components of different heights therein. The metal core layer is formed therein with through-holes 40-2, 40-3 and a counter sinking 42, which have passive components 20-1, 20-2 and an active component 22 located therein respectively. These components are connected to a wiring pattern 50 formed on wiring layers 34-1, 34-2 via a connection via 52. The contact faces of the components to the connection vias are set at the same height by the two metal layers. COPYRIGHT: (C)2006,JPO&NCIPI
