ABSTRACT:
In a piezoelectric element comprising a first electrode2provided on a substrate1, a piezoelectric material3provided on the first electrode2and a second electrode4provided on the piezoelectric material3, the piezoelectric material3is configured so as to have a perovskite type crystal structure which is represented by a formula ABO3and in which the main component for the A site is Pb and the main components for the B site are Zr, Ti and Pb, and configured so that a ratio of Pb atoms to all atoms in the B site is more than 3% and not more than 30%. Namely, the piezoelectric material3is formed so as to contain Pb excessively and the excess Pb atoms are activated to be Pb4+during formation of the piezoelectric material3and then introduced into the B site.
