PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC APPARATUS |
| 摘要 |
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.;(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) General Formula (1) |
