摘要:
A piezoelectric element comprises a piezoelectric layer and an electrode which is provided with the piezoelectric layer. The piezoelectric layer comprises a complex oxide which has a perovskite structure including bismuth, iron, a first dopant element which is at least one type selected from a group formed from sodium, potassium, calcium, and strontium, and a second dopant element which is at least one type selected from a group formed from manganese, titanium, vanadium, niobium, and tin.
