A wiring board having an excellent electrical property and reliability or the like. The wiring board includes a core board, a capacitor and a resin filler. The core board includes an accommodation hole therein and a core board main surface side conductor disposed on the core main surface thereof. A capacitor main surface side electrode is disposed on a capacitor main surface of the capacitor. A gap between the capacitor accommodated in the accommodation hole and the core board is filled with the resin filler so that the capacitor is fixed to the core board. Further, the resin filler has a main surface side wiring forming portion on which a main surface side connecting conductor, which is connected to an end portion of a via conductor, is disposed so as to connect the core board main surface side conductor to the capacitor main surface side electrode.
