Abstract
In order to provide a built-in capacitor type wiring board capable of preventing misalignment of the capacitor, a capacitor built-in type wiring board is provided which includes a core board; a multilayer portion disposed on at least one side of the core board and formed by a plurality of interlayer insulating layers; and a plurality of conductor layers alternately laminated on the core board. The capacitor is of a chip-like shape with first and second main surfaces and includes a dielectric layer; electrode layers laminated on the dielectric layer; and a hole portion opening at least at the second main surface. The capacitor is embedded in the interlayer insulating layers so that the second main surface faces the core board.
