PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC EQUIPMENT
There is provided a lead- and potassium-free piezoelectric material having a high piezoelectric constant and a satisfactory insulation property and a piezoelectric element that includes the piezoelectric material. The piezoelectric material contains a perovskite-type metal oxide having the general formula (1): (NaxBa1-y)(NbyTi1-y)O3 (wherein x satisfies 0.80≤x≤0.95, and y satisfies 0.85≤y≤0.95); and at least one rare-earth element selected from La, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, wherein the rare-earth element content is more than 0 mol % and 5 mol % or less of the amount of perovskite-type metal oxide. The piezoelectric element includes the piezoelectric material.
