PROBLEM TO BE SOLVED: To provide a liquid ejecting head, a liquid ejecting apparatus and a piezoelectric element having excellent voltage resistance. An electrode 60 uses a composition for forming a lanthanum nickelate film obtained by mixing at least lanthanum acetate, nickel acetate, acetic acid and water to obtain a mixed solution and then heating the mixed solution. A lanthanum nickelate film 62 formed by a solution method is provided, and the piezoelectric layer 70 is formed on a lanthanum nickelate film and is made of a complex oxide having at least Pb, Ti and Zr and having a perovskite structure, and an X-ray The half width (θ) of the peak derived from the (100) plane and / or the peak derived from the (001) plane measured by the rocking curve method is 6.0 degrees or less.
