摘要：
A wiring board has a wiring board main body, a solder resist and solder bumps. The solder resist is formed on a top surface of the wiring board main body, and includes first openings, and second openings that have a diameter larger than that of the first openings. The solder bumps are disposed in the first openings and in the second openings. In addition, top portions of the solder bumps disposed in the first openings have a flat face, while top portions of the solder bumps disposed in the second openings have a non-flat face.
