Piezoelectric element, multilayered piezoelectric element, liquid discharge head, liquid discharge apparatus, ultrasonic motor, optical apparatus, and electronic apparatus
A lead-free piezoelectric element that stably operates in a wide operating temperature range contains a lead-free piezoelectric material. The piezoelectric element includes a first electrode, a second electrode, and a piezoelectric material that includes a perovskite-type metal oxide represented by (Ba1-xCax)a(Ti1-yZry)O3 (1.00≤a≤1.01, 0.02≤x≤0.30, 0.020≤y≤0.095, and y≤x) as a main component and manganese incorporated in the perovskite-type metal oxide. The manganese content relative to 100 parts by weight of the perovskite-type metal oxide is 0.02 parts by weight or more and 0.40 parts by weight or less on a metal basis.
