Abstract:
A ceramic substrate for an electrochemical element that includes a ceramic layer and a high-thermal-expansion-coefficient material layer that is laminated on the surface of the ceramic layer. The high-thermal-expansion-coefficient material layer has a higher coefficient of thermal expansion than the ceramic layer, and applies compressive stress to the ceramic layer.
