Abstract
A process for producing a piezoelectric oxide having a composition (Ba, Bi, A)(Ti, Fe, M)O, where each of A and M represents one or more metal elements. The composition is determined so as to satisfy the conditions (1) and (2),0.98≦TF(P)≦1.02,  (1)TF(BiFeO)<TF(AMO)<TF(BaTiO),  (2)where TF(P) is the tolerance factor of the perovskite oxide, and TF(BaTiO), TF(BiFeO), and TF(AMO) are respectively the tolerance factors of the oxides BaTiO, BiFeO, and AMO.
