Abstract
The piezoelectric film includes a perovskite oxide which is represented by General Formula P,ABNbNiO  General Formula Pwhere A contains at least Pb, B contains at least Zr and Ti, and x and y respectively satisfy 0.1≤x≤0.3 and 0≤y≤0.75x. Although standard values of δ and z are δ=0 and z=3, these values may deviate from the standard values in a range in which a perovskite structure is capable of being obtained.
