WIRING BOARD AND METHOD OF MANUFACTURING THE SAME

摘要

A wiring board is provided. The wiring board includes: a core substrate; wiring layers formed on the core substrate; and a reinforcement conductor which penetrates through the core substrate and which is formed by flat-plate-shaped conductor portions that intersect each other in a plan view. The reinforcement conductor is formed by intersecting vertical crosspieces and horizontal crosspieces and assumes a lattice form in the plan view.
