Abstract

A wiring board includes a plurality of circular semiconductor element connection pads deposited in a lattice form onto a mounting portion of an insulation substrate, their upper surfaces being connected to electrodes of a semiconductor element. A solder resist layer is deposited onto the insulation substrate, which covers the side surfaces of these pads and exposes the upper surfaces of these pads. The solder resist layer has a concave part whose bottom surface corresponds to at least all the upper surfaces of these pads.
