Abstract

A piezoelectric material contains a first component that is a rhombohedral crystal that is configured to have a complex oxide with a perovskite structure and Curie temperature Tc1 and a second component that is a crystal other than a rhombohedral crystal that is configured to have a complex oxide with the perovskite structure and Curie temperature Tc2, in which |Tc1−Tc2| is equal to or less than 50° C.
