Abstract
The piezoelectric material of the present invention includes a main component composed of a perovskite-type metal oxide represented by Formula (1), Zn, and Mg. The content of Zn is 0.005 mol or more and 0.050 mol or less based on 1 mol of the perovskite-type metal oxide, and the content of Mg is 0.001 mol or more and 0.020 mol or less based on 1 mol of the perovskite-type metal oxide.Formula (1): (NaxBa1-y)(NbyTi1-y)O3 (where x is 0.83 or more and 0.95 or less, y is 0.85 or more and 0.95 or less, and x/y is 0.95 or more and 1.05 or less).
