Disclosed is a non-lead perovskite oxide having a low Curie temperature and high ferroelectricity represented by General Formula (P) given below. (Bix1,Bax2,Xx3)(Fey1,Tiy2,Mny3)O3(P) (where, Bi and Ba are A-site elements, X is one kind or a plurality of kinds of A-site elements, other than Pb and Ba, with an average ion valence of 2. Fe, Ti, and Mn are B-site elements. O is oxygen. 0<x1+X2<1.0, 0<x3<1.0, 0<y1+y2<1.0, 0@y3<1.0, 0<x1, 0<x2, 0<y1, 0<y2. The standard molar ratios among A-site elements, B-site elements, and oxygen are 1:1:3, but the molar ratios among them may deviate from the standard ratios within a range in which a perovskite structure may be formed.) |
