Abstract

In the present invention, a metal-ceramic composite substitute is produced by joining a metal plate to a ceramic substrate by using a brazing material in a paste form prepared by adding 10-14 parts by weight of a vehicle to 100 parts by weight of a powder of which the solid centent comprises 90.0.about.99.5% of an Ag powder, 0.about.9.5% of a Cu powder and 0.5.about.4.0% of an active metal powder, and 0.0.about.0.9% of a titanium oxide powder if necessary.
