A glass-ceramic board, comprising a co-fired product of a silver-based conductive material and a glass-ceramic insulation material containing an oxidizable metal, is new. Preferred Features: The metal is a room temperature stable or metastable metal selected from Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and Ga, especially Cu. The glass component of the glass-ceramic insulation material is selected from silicate glass, borosilicate glass and CaO-SiO2-Al2O3-B2O3 glass and the ceramic component is selected from aluminum oxide, silicon dioxide, forsterite, anorthite and wollastonite.
