<p><P>PROBLEM TO BE SOLVED: To obtain a wiring board having a built-in electric element, excellent in reliability in connection between a built-in electric element and a wiring circuit layer provided on the wiring board. <P>SOLUTION: The wiring board having a built-in electric element includes: an insulation substrate having a plurality of insulation layers formed of an organic material; and an electric element having a laminate formed by laminating a plurality of dielectric layers and inner electrodes, and outer electrodes provided on the upper surface of the laminate and electrically connected to the inner electrodes. In the wiring board, the insulation layers are each provided with a first insulation layer having a cavity having the electric element arranged therein, a second insulation layer arranged on the upper surface of the first insulation layer and having a via hole conductor electrically connected to the outer electrodes of the electric element, and a third insulation layer arranged on the lower surface of the first insulation layer, and the outer electrodes of the electric element are directly connected to the via hole conductor positioned on the outer electrodes on the upper surface of the electric element. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
