PROBLEM TO BE SOLVED: To provide a two-component piezoelectric material having excellent piezoelectric characteristic.SOLUTION: This piezoelectric material is formed by adding at least either of MnCOand CoOas a sintering aid to a compound represented by general formula (1-x)BaTiO-x(BiNa)(TiMy)O, wherein M in the general formula is Ta or Zr. When M is Ta, following inequalities are preferably satisfied: 0.05≤x≤0.15 and 0.06≤y≤0.14. When M is Zr, following inequalities are preferably satisfied: 0.05≤x≤0.15 and 0.04≤y≤0.07. |
