A piezoelectric element includes a first electrode, a piezoelectric film disposed on the first electrode, and a second electrode disposed on the piezoelectric film. The piezoelectric film is composed of piezoelectric material that is lead free and formed by mixing 100(1−x) % of material A having a spontaneous polarization of 0.5 C/m2 or greater at 25° C. and 100 x % of material B having piezoelectric characteristics and a dielectric constant of 1000 or greater at 25° C., wherein (1−x)Tc(A)+x Tc(B)≧300° C., where Tc(A) is the Curie temperature of the material A and Tc(B) is the Curie temperature of the material B.
