Embodiments provide a wiring board which is structured to be suitable for connection with components, whereby its reliability can be improved. An embodied wiring board of the invention has pads and a solder resist in which opening portions which expose the pads are formed. Protrusion-shaped members are fixed to some of the surfaces of the pads. The surfaces of the pads and the surfaces of the protrusion-shaped members are covered with solder bumps. The height of the solder bumps is larger than the height H1 and H2 of the protrusion-shaped members. The opening portions have different inner diameters, and the volume of the protrusion-shaped members increases as the diameter of the opening portion decreases.
