An electrode is provided with a lanthanum nickelate film which is formed through a chemical solution deposition method using a lanthanum nickelate film forming composition which is obtained by heating a mixed solution obtained by mixing at least lanthanum acetate, nickel acetate, acetic acid, and water, a piezoelectric layer is provided on the lanthanum nickelate film and is formed of a complex oxide having a perovskite structure which contains at least Pb, Ti, and Zr, and a half-width (&thetas;) of a peak derived from a (100) plane and/or a peak derived from a (001) plane measured using an X-ray rocking curve method is 6.0 degrees or less. |
