Abstract
According to the present invention, on a double-sided substrate, a plurality of through-holesconnected to one wirefor plating as well as wiring are collectively arranged within a narrow range close to the connection portion. After a plating process, a penetrating holeis formed and the connection potion is cut off. Thus, the wirefor plating and the collectively arranged through-holesare made independent of one another so that no electric conduction occurs among the wirefor plating and the through-holes
