摘要:
There is provided a lead-free piezoelectric material having a satisfactory piezoelectric constant and mechanical quality factor in the range of device operating temperatures (from −30° C. to 50° C.). The piezoelectric material contains a main constituent containing a perovskite-type metal oxide expressed by the general formula (Ba1-xCax)a(Ti1-yZry)O3, where x, y and a satisfy the 0.030≦x
