Abstract

See full text

A piezoelectric element includes a first electrode, a piezoelectric layer which is formed on the first electrode by using a solution method, and is formed from compound oxide which has a perovskite structure in which potassium, sodium, and niobium are provided, and a second electrode which is provided on the piezoelectric layer. The piezoelectric layer has a peak derived from a (200) plane and a peak derived from a (002) plane in an X-ray diffraction pattern obtained by θ-2θ measurement.
