Provided are a piezoelectric material that does not use lead and potassium, has a high Curie temperature, has a good mechanical quality factor, and has high stability during long-term driving, and a piezoelectric element using the same. SOLUTION: General formula (1): Na x Ba 1-y Nb y Zr 1-y O 3 (wherein x is 0.85 ≦ x ≦ 0.96, y is 0.90 ≦ y ≦ 0. 96.) and a piezoelectric element using the same, and the piezoelectric material 2 contains a perovskite metal oxide, Cu, and a Cu content. However, it is preferable that it is 2.00 mol% or less with respect to 1 mol of perovskite type metal oxides. [Selection] Figure 1 |
