The present invention provides a lead-free polymer composite piezoelectric material having excellent piezoelectric performance. The present invention is made of a matrix 12 made of an organic polymer resin and a perovskite oxide having a composition represented by the following general formula (PX) contained in the matrix 12 (which may include an unavoidable impurity): piezoelectric 11 It provides a polymer composite piezoelectric body (1) comprising a. (Bi x , A 1-x ) (B y , C 1-y ) O 3 ... (PX) [In formula (PX), A is an A-site element having a divalent average ion valence other than Pb, B is a B-site element having an average ion valence trivalent, C is a B-site element having an average ion valence greater than trivalent, and A, B And C are one or a plurality of metal elements, respectively. O is oxygen. B and C are different compositions. 0.6≤x≤1.0, x-0.2≤y≤x.] |
