Abstract

A glass-ceramic wiring board includes an insulating substrate, a via disposed in the insulating substrate and a via interconnection filling the interior of the via. The via interconnection is sintered material having metal particles. The metal particles have a cross-sectional area per one metal particle surrounded by a metal particle boundary of less than 2000 &mgr;2, which can be determined by cutting, etching and examining a cross-section of the via.
