Abstract:
1. A wiring board, comprising; a multilayer substrate having a first main substrate surface and a second main substrate surface opposed to the first main substrate surface, the first main substrate surface including a chip mounting area to which an electronic chip is mounted; and a reinforcing member comprising a body and a plurality of capacitors incorporated inside the body, the body being predominantly formed of ceramic material and fixed to an area of the first main substrate surface other than the chip mounting area, the reinforcing member defining an opening, the opening exposing the chip mounting area, wherein the plurality of capacitors are laminated capacitors comprising first electrode layers, second electrode layers, and ceramic layers alternately laminated together; wherein the first electrode layers of the respective capacitors are formed as a plurality of electrically independent electrode patterns in the same layer; and wherein the second electrode layers of the respective capacitors are formed as a plurality of electrically independent electrode patterns in the same layer.
