ABSTRACT:
A wiring board of the present invention includes a dummy wiring in a semiconductor-chip mount area on which a semiconductor chip is to be mounted. The dummy wiring is arranged in a manner such that all wiring-lines included in the dummy wiring each have a free end within the semiconductor-chip mount area. This prevents a defect due to vaporization and expansion of moisture inside a semiconductor apparatus, with a simple structure and without raising costs.
