Abstract:
A method for producing a ceramic substrate comprising the steps of:forming a hole in a ceramic green sheet;filling the hole with a conductive paste comprising: about 80-94 wt. % of spherical or granular conductive metal powder having a particle size of about 0.1-50 .mu.m, about 1-10 wt. % of resin powder which swells in a solvent contained in the conductive paste and has a particle size of about 0.1-40 .mu.m, and about 5-19 wt. % of an organic vehicle comprising a solvent;laminating the ceramic green sheet having the hole filled with the conductive paste together with other ceramic green sheets to form a laminated body; andfiring the laminated body.
