Abstract
Disclosed is a dielectric paste for a ceramic multilayer wiring substrate, of which feature, among others, lies in the composition of inorganic components comprised of ceramics made of Al.sub.2 O.sub.3, SiO.sub.2, CaO and MgO, and a borosilicate glass. This can be prepared by mixing a part of the glass with the ceramic, calcining the mixture at a high temperature, and then adding the remaining glass to mix with the calcined product. The insulation layer is densely formed, and a dielectric paste excelling in electric insulating property can be obtained by mixing this composition with an organic liquid.
