Verfahren zur Herstellung einer Mehrschicht-Schaltkreiskarte

A multilayer circuit board, in which a plurality of insulating layers and a plurality of conductive layers, each of which includes a conductive pattern, have been laminated, includes an insulating layer, a conductive compound, and a conductive pattern. The insulating layer has a trench. The conductive compound is located in the trench. The conductive pattern adjoins the trench and is electrically connected to the conductive compound. The conductive pattern and the conductive compound make up a conductive wire that has a higher current-carrying capacity than the conductive pattern.
