Liquid ejecting head, liquid ejecting apparatus, and piezoelectric element |
摘要 |
A liquid ejecting head includes a piezoelectric element including a first electrode, a piezoelectric layer overlying the first electrode with an orientation control layer therebetween, and a second electrode overlying the piezoelectric layer. The piezoelectric layer is made of a complex oxide having a perovskite structure including an A site containing lead and a B site containing zirconium and titanium. The orientation control layer is made of a complex oxide having a perovskite structure including an A site containing lanthanum and a B site containing nickel and titanium. |
