Zusammenfassung:	In a wiring board, a first substrate (10), a surface electrical conductor layer (12), and a second substrate (20) are laminated in this order. The second substrate (20) contains an organic material as an insulating base material. The surface electrical conductor layer (12) is located on a surface of the first substrate (20), and the second substrate (20) includes a plurality of interlayer connection conductors (22). The insulating base material of the second substrate (20) includes a first region (211) and a second region (212). The first region (211) is located on the surface electrical conductor layer. The second region (212) is located on the surface of the first substrate. The first region (211) has a lower ratio of voids and pores than the second region (212).
