PROBLEM TO BE SOLVED: To provide a liquid ejecting head and a liquid ejecting apparatus in which cracks in a diaphragm on a boundary between a piezoelectric active section and a piezoelectric nonactive section are suppressed. SOLUTION: A piezoelectric element 300 comprises a first electrode 60 which is an individual electrode, a piezoelectric layer 70, and a second electrode 80 which is a common electrode. The piezoelectric element includes the piezoelectric active section 320 and the piezoelectric nonactive section 330 so as to face pressure generating chambers 12. The piezoelectric nonactive section 330 extends to the outside of the pressure generating chambers 21. On the piezoelectric layer 70 of the piezoelectric nonactive section 330, a stress controlling layer 100 is provided, which has internal stress in the same direction as internal stress of the second electrode 80 and is electrically insulated from the second electrode 80.
