A wiring board includes: an insulating substrate; a plurality of conductive wirings provided on the insulating substrate so as to be aligned with a semiconductor mounting region where a semiconductor chip is to be mounted; and bump electrodes provided on the respective conductive wirings. The bump electrodes include a first bump electrode for mounting the semiconductor chip and a second bump electrode for adjusting a height of the first bump electrode. The second bump electrode is provided at a region of at least one of the plurality of conductive wirings other than the semiconductor mounting region.
