Claim Text:
1. A wiring board, comprising: a first insulation layer; a plurality of first conductive patterns formed on the first insulation layer and including a plurality of first mounting pads positioned to mount a first semiconductor element and a second semiconductor element on the first insulation layer; a wiring structure positioned in the first insulation layer and comprising a second insulation layer, a plurality of second conductive patterns formed on the second insulation layer, and a plurality of second mounting pads connected to the second conductive patterns; and a plurality of third mounting pads formed on the first insulation layer above the second mounting pads and connected to the second mounting pads, the plurality of third mounting pads is positioned to mount the first semiconductor element and the second semiconductor element on the first insulation layer such that a plurality of first pads of the third mounting pads is shifted away from the plurality of second mounting pads in a horizontal direction perpendicular to a lamination direction and positioned to face a plurality of conductive pads of the first semiconductor element, respectively, and a plurality of second pads of the third mounting pads is shifted away from the plurality of second mounting pads in the horizontal direction and positioned to face a plurality of conductive pads of the second semiconductor element, respectively.
