A glass ceramic substrate is formed on a glass ceramic insulating layer with a conductor connecting a plurality of circuit patterns which are to be independent of each other as to electrical function. Baking the glass-ceramic insulating layer with the conductor, and opening by cutting after baking, forms a plurality of independent circuits with improved electrical resistance between them.
