PIEZOELECTRIC ELEMENT, METHOD OF MANUFACTURING THE SAME, FLUID INJECTION HEAD, AND FLUID INJECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric element which improves an element property.

SOLUTION: In a piezoelectric element 130, equipped with: a piezoelectric layer 70 formed on a base; and a primary electrode 60 and a secondary electrode 80 which are formed on the piezoelectric layer 70, the piezoelectric element 130 is made to be characterized in that at least one of the primary electrode 60 and the secondary electrode 80 is formed in a side end surface of the piezoelectric layer 70.
