PROBLEM TO BE SOLVED: To provide a liquid-ejecting head having a piezoelectric element with a small environmental load and a large amount of strain, and to provide a liquid-ejecting apparatus, a piezoelectric element and a piezoelectric material.SOLUTION: The liquid-ejecting head I includes a pressure-generating chamber 12 communicating with a nozzle opening 21, and a piezoelectric element 300 having a first electrode 60, a piezoelectric layer formed on the first electrode, and a second electrode formed on the piezoelectric layer. The piezoelectric layer consists of a perovskite complex oxide containing Bi, La, Fe, and Mn and exhibits electric-field-induced phase transition. |
