Abstract
Provided is a method of manufacturing a liquid ejecting head including a pressure generating chamber communicating with a nozzle opening and a piezoelectric element including a piezoelectric layer and an electrode, the method including: forming a first piezoelectric precursor film containing Bi and Fe, or Ba and Ti; forming a first piezoelectric layer by heating and crystallizing the first piezoelectric precursor film; forming a second piezoelectric precursor film further containing at least one selected from Li, B, and Cu on the first piezoelectric layer, in addition to Bi and Fe, or Ba and Ti contained in the first piezoelectric precursor film; and forming the piezoelectric layer by heating and crystallizing the first piezoelectric layer and the second piezoelectric precursor film.
