Abstract:
The present invention provides a lead-free piezoelectric material having a high piezoelectric constant and a high mechanical quality factor in a wide operating temperature range. The piezoelectric material includes a perovskite-type metal oxide represented by Formula (1): (Ba 1-x Ca x ) a (Ti 1-y Zr y ) O 3 (1.00 ≤ a ≤ 1.01, 0.125 ≤ x
