Claim:
A perovskite oxide, comprising a first component represented by General Formula (P1) given below and a second component represented by General Formula (P2) given below, (Bi x1 , X x2 ) (Fe z1 , Mn, 2 )O 3 (P1) (A y1 , Y y2 )BO 3 (P2) wherein, Bi is an A-site element and X is an A-site element with an average ion valence of not less than four; A is one or a plurality of A site elements other than Pb with an average ion valence of two; Y is a one or a plurality of A-site elements with an average valence of not less than three; Fe and Mn are B-site elements, and B is one or plurality of B-site elements with an average ion valence of four; O is oxygen; 0.6≦x1<1.0, 0≦x2≦0.4, 0.6≦y1<1.0, 0≦y2≦0.4, x2+y2>0, 0.6≦z1<1.0, 0≦z2≦0.4; the standard molar ratios among A-site elements, B-site elements, and oxygen are 1:1:3, and the standard molar ratios among them can deviate from the standard molar ratios within a range which is capable of forming a perovskite structure.
