Abstract:
A piezoelectric element comprises a first electrode including platinum, a piezoelectric layer disposed above the first electrode, made of a complex oxide having a perovskite structure containing at least bismuth, and a second electrode disposed above the piezoelectric layer. An oxide containing bismuth and platinum is disposed at the interface of the piezoelectric layer with the first electrode.
