Abstract:
This ceramic substrate is provided with: a ceramic element having a ceramic layer on the surface; and a surface electrode that is provided on one main surface of the ceramic element. The ceramic substrate is characterized in that: an oxide layer formed of an insulating oxide is formed between the surface electrode and the ceramic layer, said oxide having a melting point that is higher than the firing temperature of the ceramic layer; the oxide layer is also provided on a ceramic layer portion where the surface electrode is not provided; and the surface of the oxide layer on the ceramic layer portion where the surface electrode is not provided is a rough surface.
