| 摘要 | 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. | ||

| 主权项 | 1. A piezoelectric material containing: a first component that is a rhombohedral crystal that has a complex oxide with a perovskite structure and Curie temperature Tc1; and a second component that is a crystal other than a rhombohedral crystal has a complex oxide with the perovskite structure and Curie temperature Tc2, wherein the piezoelectric material is obtained by forming a solid solution of the first component and the second component, and an absolute value of a difference between Tc1 and Tc2 is equal to or less than 50° C. | ||
