Abstract

A high-dielectric lead-free paste serves for the manufacture of at least one area having a high dielectric constant in a ceramic multilayer circuit. The lead-free dielectric paste is basically made of barium titanate nano powder of a suitable particle size and sinters at temperatures below 1000.degree. C., preferably in a range of 800.degree. C. to 1000.degree. C.
