LAMINATED CIRCUIT BOARD AND BOARD PRODUCING METHOD

摘要

A laminated circuit board includes a first wiring board that has a first land formed on a surface thereof; a second wiring board that has a second land formed on a surface thereof; a bonding layer that is laid between the first wiring board and the second wiring board and electrically connects the first land and the second land via a conducting material; and a plate that has a through-hole through which the first land is connected to the second land, wherein a diameter of the through-hole of the plate is larger than a diameter of a component that is made by filling the conducting material.
