Abstract:
The present invention provides a piezoelectric material not containing lead and potassium, having a high relative density, a high Curie temperature, and a high mechanical quality factor, and exhibiting good piezoelectricity. The piezoelectric material contains 0.04 percent by mole or more and 2.00 percent by mole or less of Cu relative to 1 mol of metal oxide represented by General formula (1) below. General formula (1) ((Na 1-z Li z ) x Ba 1-x )(Nb y Ti1 -y )O 3 (in Formula, 0.70 x ≤ 0.99, 0.75 ≤ y ≤ 0.99, and 0
