Zusammenfassung:	Provided is a ceramic substrate for an electrochemical element, which is unlikely to be broken when thermal stress or mechanical stress is applied The ceramic substrate for an electrochemical element, which includes: a ceramic layer 11a; and a high-thermal-expansion-coefficient material layer 11b that is laminated on the surface of the ceramic layer 11a and higher in coefficient of thermal expansion than the ceramic layer 11a, where compressive stress from the high-thermal-expansion-coefficient material layer 11b is applied to the ceramic layer 11a.
