Abstract:
A liquid-ejecting head includes a pressure-generating chamber communicating with a nozzle opening and includes a piezoelectric element including a piezoelectric layer and electrodes. The piezoelectric layer contains bismuth sodium potassium titanate and satisfies the inequality 0≦Pr/Pm≦0.25 at 25° C., where Pm and Pr are the saturation polarization and remanent polarization, respectively, of the piezoelectric layer.
