Claim:
1. A wiring board, comprising: a core including a first surface and a second surface facing each other; a first portion and a second portion disposed on the first and second surfaces, respectively, wherein each of the first and second portions comprises a plurality of insulating layers and a plurality of wiring layers stacked in an alternating manner; at least one capacitor disposed in at least one interior region, wherein the at least one capacitor comprises a first electrode thicker than the core and a second electrode thicker than the core, and wherein the at least one interior region exposes a portion of the core and a portion of the first portion adjacent to the core; and at least one first via electrically connecting one of the wiring layers of the first portion with the first and second electrodes, wherein a surface of the first and second electrodes is in contact with the at least one first via, wherein thicknesses of the first and second electrodes are larger than a sum of a thickness of the core and a thickness of an insulating layer which is included in the first portion and which is closest to the core, and wherein an insulating layer which is included in the second portion and which is closest to the core covers the second surface of the core and bottom surfaces of the first and second electrodes.
