PIEZO-ELECTRIC ELEMENT AND PIEZO-ELECTRIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a piezo-electric element and a piezo-electric component, which are not influenced from a loss caused by conductivity in a real usage temperature range of the piezo-electric part even if they are under high temperature circumstances. SOLUTION: The piezo-electric element includes: a polarized piezo-electric substrate; each electrode formed on positive and negative pole sides in the polarized direction of the piezo-electric substrate; and a temperature sensing semiconductor formed on the piezo-electric substrate and having a negative resistance temperature coefficient for connecting the respective electrodes electrically.
