PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC APPARATUS
The present invention provides a lead-free piezoelectric material having a high piezoelectric constant over a wide operating temperature region. Therefore, the present invention relates to a piezoelectric material including a perovskite-type metal oxide represented by general formula (1) below as a main component, wherein the average valence of Sn contained in the general formula (1) lies between 2 and 4. General Formula (1) (BavCawSnxTiyZrz)O3 (where 0.620 ≤ v ≤ 0.970, 0.010 ≤ w ≤ 0.200, 0.030 ≤ x ≤ 0.230, 0.865 ≤ y ≤ 0.990, 0 ≤ z ≤ 0.085, and 1.986 ≤ v + w + x + y + z ≤ 2.100)
