Abstract
A piezoelectric material is expressed as a mixed crystal including a first component formed of a complex oxide having a perovskite structure and a rhombohedral structure and containing Bi in an A-site and Fe in a B-site, a second component formed of a complex oxide having a perovskite structure and a tetragonal structure and containing Ba in an A-site and Ti in a B-site, and a third component formed of a complex oxide having a perovskite structure and a tetragonal structure and containing Bi and K in an A-site and Ti in a B-site.
