A perovskite oxide represented by a general expression, (Aa, Bb)(Cc, Dd, Xx)O3. (where, A: an A-site element, A=Bi, 0<a, B: one or more types of A-site elements, 0≦̸b<1.0, C: an B-site element, C′Fe, 0<c<1.0, D: one or more types of B-site elements, 0≦̸d<1.0, 0<b+d, X: one or more types of B-site elements, the average valence of which is greater than the average valence of C and D in chemical formula, 0<x<1.0, (average valence of A-site in chemical formula)+(average valence of B-site in chemical formula)>6.0, 0: oxygen, and standard molar ratio among A-site elements, B-site elements, and oxygen is 1:1:3, but it may deviate from the standard within a range in which a perovskite structure is possible.) |
