[PROBLEMS] reducing the environmental impact, and high piezoelectric properties, dielectric properties over a wide operating environment temperature range, and the piezoelectric material is the Curie temperature is high, and the piezoelectric element, a liquid-jet head using the same, a liquid-jet apparatus, ultrasound sensors, piezoelectric It provides a motor and a power generator.
[MEANS FOR SOLVING PROBLEMS] rhombohedral (rhombohedral crystal) and also the Curie temperature Tc1 of Fe lobe and a second component, a rhombohedral crystal other than the information layer composed of composite oxide having a Perovskite - Type structure also the page Grove the Curie temperature Tc2 Sky and a second component made of a composite oxide having a teuhyeong structure, wherein a is the same crystal system and the second component further contains a third component made of a composite oxide having a perovskite teuhyeong structure the Curie temperature Tc3, wherein Tc1 is the higher than Tc2, the Tc3 is more than the Tc1.
