Abstract
A ceramic substrate composition is provided which can be co-fired with a low-melting metal and exhibits excellent dielectric characteristics at high frequencies, particularly tens of gigahertz. The ceramic substrate composition mainly contains a glass represented by aBO-bReO-cZnO, wherein the molar ratios (a, b, and c) fall within a region defined in a ternary composition diagram by Point A (0.4, 0.595, 0.005), Point B (0.4, 0.25, 0.35), Point C (0.52, 0.01, 0.47), Point D (0.9, 0.005, 0.095), and Point E (0.9, 0.09, 0.01).
