Provided are a liquid ejecting head, a liquid ejecting apparatus, and a piezoelectric element that have a small environmental load and suppress the occurrence of cracks. A piezoelectric element includes an elastic film, an adhesion layer, a first electrode, a piezoelectric layer, and a second electrode. The piezoelectric layer includes at least bismuth, barium, iron, And a perovskite-type composite oxide containing titanium, and the molar ratio of titanium to barium (Ti / Ba) is 1.17 or more and 1.45 or less.
