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 semiconductor element; 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 such that the plurality of third mounting pads is positioned to mount the semiconductor element and forms a distance L4 between adjacent first and third mounting pads which is greater than a distance L1 between adjacent first mounting pads or a distance L5 between adjacent first and third mounting pads which is greater than a distance L2 between adjacent first mounting pads, wherein the plurality of third mounting pads is positioned such that the third mounting pads are horizontally shifted in a same direction from the plurality of second mounting pads toward the semiconductor element.
