A polymer composite piezoelectric material (1, 1a, 1b) is formed, which includes a matrix (12a, 12b) of an organic polymer resin, and a piezoelectric material (11a, 11b) included in the matrix (12a, 12b). The piezoelectric material (11a, 11b) contains a perovskite oxide having a composition represented by general formula (PX) below:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ (Bi x , A 1-x ) (B y , C 1-y )O 3 €ƒ€ƒ€ƒ€ƒ€ƒ(PX),
wherein A represents an A-site element with an average ionic valence of two other than Pb, B represents a B-site element with an average ionic valence of three, C represents a B-site element with an average ionic valence greater than three, each of A, B and C is one or two or more metal elements, O is oxygen, B and C have different compositions from each other, 0.6 ‰¤ x ‰¤ 1.0, and x-0.2 ‰¤ y ‰¤ x. |
