摘要：
A lead-free piezoelectric material that has stable, excellent piezoelectric constant and mechanical quality factor in a wide operating temperature range is provided. A piezoelectric material include a perovskite-type metal oxide represented by (Ba1-xCax)a(Ti1-yZry)O3 (where 1.00≦a≦1.01, 0.155≦x≦0.300, 0.041≦y≦0.069) 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 0.12 parts by weight or more and 0.40 parts by weight or less on a metal basis.
