    摘要: A wiring board includes a conductor formed on an inner wall of a through hole made in a core board, resin formed inside the conductor in the through hole, and, for example, a land formed over the conductor and the resin. Vias are formed over the land. The vias are connected to a plurality of connection regions of the land extending over the conductor and the resin in the through hole. The land is held by the vias connected to the plurality of connection regions. This controls the thermal expansion of the resin to a land side and therefore prevents a fracture of the land.
